We love to see our parts installed and used on client’s cars. Race car driver and Datsun Historian Glenn Chiou is running our Z Car Garage CV Axles in this 1968 Datsun 510 U2.5L Trans-Am race car!


Glenn was preparing to debut his freshly restored 510 for the 2022 Velocity Invitational event at Laguna Seca. A half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. Glenn installed the set himself with ease:

 

We also provided dyno tuning services to prepare him for the race weekend. The fresh Rebello L18 with Solex/Mikuni 44phh induction and BRE intake made great power.

 

Listen to this 510 make sweet L-Series music on our dyno in the video below. There is also race/paddock action with Glenn behind the wheel:

 

Privateer Spirit


We are happy to report that Glenn successfully raced at the Velocity Invitational event. It’s worth noting like privateers of the period, Glenn builds his race cars, maintains and manages racing efforts himself. Not an easy task so we applaud his passion and work ethic. Glenn builds some beautiful Datsuns and this historically-significant 510 is a shining example.

Glenn championed a vintage race group dedicated to the Historic B&C Sedan class and organized a “Celebration of the Two Five Challenge” display at the 2022 Velocity Invitational event. Two of the most iconic cars were present: the ex-Morton #46 BRE Datsun 510 (with Pete Brock below) and ex Kwech #3 Wetson’s Alfa. Yes that is Glenn with the legendary John Morton! Let’s take a look at the history behind Glenn’s Trans-Am 510 before we get into the restoration:

 

The Ex-Finn/Harris U2.5L Datsun 510

 

Glenn has a passion for re-telling the stories of legendary privateer Datsun racers and his penultimate restoration project was this 1968 Ex-Finn/Harris U2.5L Datsun 510, serial number PL510-023047. It is one of very few surviving cars that competed in the SCCA Trans-Am Two-Five Challenge, or more commonly known as the Under 2.5 Liter Series.

 

In 1972, Bob Finn acquired the car from a used car dealership in Santa Barbara, California. The car was sponsored by Bob Nolan Datsun and Chuck’s Shell Service in Santa Maria, California. Competition Street and Rally (CSR) Racing, a shop Finn ran out of Chuck’s Shell Service, prepared the car for competition. It is one of two cars in which an entire package of go-fast parts were purchased from Brock Racing Enterprises in El Segundo, California, as part of their “BRE kit car” program. Mac Tilton, then BRE Crew chief and engineer – later Tilton Engineering, developed the suspension and provided all machine work. Bob Finn and Ron Harris began racing #37 in late 1972.

 

Its first two races were the two final races of the 1972 SCCA Trans-Am Two-Five Challenge season at Laguna Seca and Riverside International Raceway, finishing 15th and 23rd. Unfortunately 1972 would see the end of the Trans Am Two-Five Challenge, but that would not stop Finn and Harris from continuing to race the car. They competed throughout the 1970’s in the SCCA B-Sedan class both regionally and nationally with numerous first place finishes, often beating out factory race teams. While Riverside International Raceway was its home race track, the car could also be seen racing at Willow Springs International Raceway, Laguna Seca Raceway, Sears Point, Portland International Paceway, Ontario Motor Speedway.

 
 

In that time, Finn and Harris competed against the likes of John Morton, Horst Kwech Harry Theodoracopoulos, Bobby Allison, Walt Mass, Dave Madison, Corky Bell, Norm Balzer, Pat Daily, and many other prominent racers. Bill and Jack Johnston acquired the car in 1979 and would go on to race the car for the next 33 years. Bill Johnston and Steve Dragus shared driving duties, while Jack was the crew chief. Dragus, who was best known for the building engines for Don “The Snake” Prudhomme, prepared the engines. Johnston and Dragus won three regional Cal Club Championships in the 1980’s, and would go on to win the last SCCA GT4 national race at Riverside Raceway before the track closed in 1989.

Restoration

 

The Ex-Finn/Harris Datsun 510 was not always in the orange livery shown above. When Glenn acquired the car several years ago it was red and he ran with this livery at many vintage racing events…until it was time to restore it back to its former glory…

 

Glenn is no stranger to vintage race car restoration. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this car himself and it is now back to the Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas. Glenn also restored the Different Drummer Racing Z raced by Greg Sorrentino. This IMSA GTU Datsun 260Z features our Z Car Garage CV Axles and dyno tuning:

 

The 510 was dissembled for paint and bodywork, using period photos to guide the livery hand-applied by the talented Real Ralph:

 

As usual, Glenn’s painstaking efforts and diligence result in a faithful restoration…where parts are not available he has gone to extraordinary lengths to re-create pieces or use period-correct/surviving parts with archival guidance…shown below: vintage SW oil cooler, BRE remote oil adapter, expansion tank and BRE intake manifold:

 

Glenn assembled the interior with Mil-spec switches & motorsports grade wiring:

 

The fresh Rebello L18 is about to be installed…all done by Glenn himself in his home garage:

 

I was lucky to visit Glenn to see the restoration in-progress and it was simply a feast for the eyes…plated chassis parts, cool bits of history everywhere…plus the BADD 240Z nearby 🙂

 

Datsuns Are Driven!


With the restoration complete, Glenn has been enjoying the Ex-Finn/Harris U2.5L 510 at vintage racing events throughout the year. Follow his racing adventures on Instagram with more photos in the gallery below:

The fifth annual HSR Classic 24hr race at Daytona International Speedway was held November 13-17. Racing legend John Morton and co-driver Rob Fuller piloted the #46 BRE Datsun 240z owned by team manager Randy Jaffe.
.

Enjoy our report from the event with pictures, video and commentary from Rob and Randy!

 

Hallowed Ground: #46 Debuts at Daytona Speedway

 

When the BRE 240z was not accepted into the 2019 Rolex Monterey Motorsports Reunion team owner Randy Jaffe was anxious to find a Fall event. Thanks to Michael Eberhardt of Vintage Racing Co. we were able to run the Classic 24 and share a garage with him at Daytona. It was an amazing feeling sharing the same hallowed grounds where all the pros raced for years.

 

Rob: “This is a relatively new event and HSR’s efforts to make it larger were clear: the Classic 24 had people from all over the world (1/3 from Europe), and famous drivers and cars everywhere: Gunnar Jeannette, Derek/Justin bell, Jochen Maas, Daytona prototypes, LMP cars, vintage IMSA cars, 935s and big-boy hardware.”

Paddock pictures from top left to bottom right: AC/DC lead singer Brian Johnson with Rob Fuller, Gunnar Racing Team, VM columnist Jochen Maas and a 1955 300SL, 1985 Porsche 962 HR1 piloted by team of Derek Bell, Justin Bell, Rodrigo Sales, and Gunnar Jeannette.

 

Enjoy this video of the sights and sounds at Daytona:

 

Racing at Daytona

    
 

The Classic 24 race features six race groups with 4 (1hr) sessions and cumulative time deciding the winner. Each session has a 3-minute pitstop with mandatory driver exit during fueling. There were many challenges facing the ZCG team as we prepped the BRE 240Z for big banking of Daytona:

Rob: “Josh Corwin prepped gear ratios for the diff and we went there armed for any scenario. At 3.56 miles, Daytona is much longer than our West Coast tracks so we built a 3.54 and 3.36. After one practice session we realized the 3.36 was needed.”

 

It was an incredible sight to see the #46Z out on the high banking with serious race cars like the Smith Motorworks 1980 Porsche 935 K3:

 

To aid driving during night sessions the Z was fitted with LED lamps:

 

Despite heavy rain the team carried on, making changes to the car and improving with each session.

Rob:  “There were 12 cars in our group with a bunch of 911s and 914s. The Z worked flawlessly.  We made a last minute carb change, sent pics of the spark plugs to Dave Rebello, and we were pumped for it. The sheer size of the stands and banking was overwhelming but we welcomed the challenge!”

Randy:  “As you drive into the infield at Daytona and look at that 31% banking it’s super intimidating and as Rob stated you cannot look straight out of the car as it’s always bending left and he has never experienced that before. Rob did an amazing job of adapting to not only the car but to the track within 2 to 3 laps as he had cut down six seconds plus. John Morton has not run Daytona in over 20 years and he got right in the car and turned a great time which is what professional race drivers do! At 77 years old it’s just amazing how he is so calm and so smooth around these tracks!”

 

Remember those those mandatory pitstops? Thanks to the ZCG team (Josh/Keith) all stops were nailed and we actually had to wait because we were under time.  We also had help from Randy’s friend Barney to help with fueling, and Chris Karl from SCCA. A rally of people excited to see the Z at Daytona all pitched in.

 

The bad weather and lack of track experience didn’t hold John or Rob back. We started 10th in class in the 1st session and by the end of the 1st leg we were in 3rd place.

 

From 10th to 3rd in one session is impressive with John and Rob turning near-identical lap times. Rob was ecstatic not only about the Z’s performance, but also being able to co-drive with his hero:

Rob:Ben from Retrosport with Alan Terpins’ 1979 Porsche 935 MOMO car kicked ass and won their class.  They were clocked on the front straight under braking at 188mph. The BRE Z did 156mph top speed and our lap times (Morton and Fuller) were within a .1 of each other. I can’t describe the feeling of going from total fanboy to being a co-driver with John Morton. All of this comes from Randy Jaffe’s generosity, drive/passion to celebrate this car and era. These heroes that were making history and didn’t even know it 50years later. All while a new crop of people that love and appreciate this car. Watching people from all over the world come over to find John Morton to have him sign something, shake his hand, tell him a Datsun story. It’s surreal.”

 

Unfortunately our hopes of a first or second place finish in class were cut short at the second session. John Morton got an epic start and as they all went into turn 1 on the first lap (at night) a Lola T 70 lost its grip, then a Chevron panicked and cut hard right in front of John. There was nothing he could do and the car was so low that it flipped us up in the air and onto the roof:

 

John Morton was able to exit the Z safely, without any injuries. The Z was towed in, covered and our race ended. We all had hashbrowns and coffee late night at Waffle House. The next morning Josh and Rob set the tow on the front of the car, took plugs out and turned it over. We actually got to drive it around paddock Sunday morning, knowing we would be back again to take a run at the high banks of Daytona.

Randy: “Most historic race cars have been wrecked so many times and put back together and we will do the same after this Daytona accident. Just a slight bump in the road but we will come back stronger as we have learned and we will continue to write more current history with John at the wheel. We can’t wait until Daytona next year where Rob and John can finish the 24 hour that we started this year.”

Here is a video with in-car footage of both John Morton and Rob Fuller. Enjoy the triple-Mikuni carb’d music and wild banking of Daytona!  At the end is multiple-angle footage of the crash:

 

The BRE 240Z will be rebuilt at Z Car Garage

 
 

We welcomed back the #46Z to ZCG for a rebuild after damages from the Daytona crash. Stay tuned for progress updates:

Randy: “The car is being shipped to Z car garage on December 13th for repairs and to prep the car for the Walter Mitty races in Atlanta in April. The most amazing part of the fun we’ve had with this car over the past three years is the excitement that Peter Brock and John Morton have shared with all of us to turn back the Hands of time! I think because of social media John Morton may actually be more famous now than he was back in the day and he often thanks me for the efforts to make his accomplishments recognized over and over which he certainly deserves! What 77-year-old race car driver do you know still flies airplanes and rides dirt bikes, jeeps and works out!! Of course none of this would happen without Rob Fuller and Josh Corwin they have been the glue behind us entire program and I would’ve never done any of this without them. Rob takes control of many situations that could be stressful and makes things easier for me!”

 

At 77 years of age John Morton is still formidable behind the wheel!

 
 

Randy was and continues to be supremely enthusiastic about the Z, John Morton and BRE. His words from Daytona:

“Per usual our pit area always had fans coming up and wanted to know where John was to talk to him and get an autograph as he had raced with many of these legends for the past five decades! I really love the story about Peter Brock and the BRE team and what John accomplished in a short period of time and still lives in high racing lore! Every piece of history from this time s fun for me to gather and collect as all of it is a part of the story!”

Randy and the BRE 240Z Build

While many have seen the BRE 240z at racing events and shows, there is a great story behind this car as told by owner Randy Jaffe:

“I met John somewhere around 2012 and told him I was going to build a tribute to his championship 240 Z car and I’m sure he’s heard that hundreds of times and he was kind of bored with the conversation. Then I started sending him and Peter Brock emails to build it correctly then after I spent several years at an attempt to do a tribute I was with both of them one night and asked about the real story on the remains of the original car. Both of them looked at each other and back at me and I was like – what was that look for? They went on to tell me that the story I had heard for years about the car being totally destroyed and no longer around was not true. Dan Parkinson who lived about a hour and a half north of Los Angeles had the remains of the car that he had re-bodied after a 1977 ball joint failure at phoenix motor Speedway. Casey Mollett – another Datsun racer back in the day was a few hundred yards behind Dan Parkinson when he hit that wall and he was part of the teardown and reassembly to the 1977 to 80 Z that Nissan gave Dan to rebuild a car. They were going to repair the original 46Z which now wore the number five livery of Dan Parkinson but the painter said it would take a month and a half to two months and they had to race in a few weeks so they use the 1977 280 Z that Nissan gave Dan.”

 

“The long and short of it is that they raced the 1977 shell for a few years and retired the car and racing in 1979 and all of those parts just sat there until 2016. Dan and I have had conversations for over a year and many many people were trying to buy these parts because they knew what they were but for some reason he felt comfortable and asked me one day do I really want all the stuff and of course I said yes. John Morton actually said since he owned the original chassis plate which he had taken off the car when he installed the remote Traco oil filter back in 1970 he kept that Vin plate in his toolbox until he gave it to me at the Petersen Museum in 2016. I had already completed my car as a tribute to the BRE team and John Morton when Dan sold me all of the surviving pieces. I then ripped the entire car apart and installing every little piece I could that had integrity and that’s when Rob Fuller stepped in to finish the car build like it was back in the day.”

Pictures from the race prep of Randy’s Z at Z Car Garage:

 
 

A sampling of the original parts is shown below including the exhaust header with megaphones, SW gauges, and BRE remote oil filter/cooler. Original BRE heat shield and fuel block pictured above.  All assembled by the crew at ZCG prior to testing:

   
 
 

Randy’s fanatic attention to detail and our team’s prep culminated in John Morton enjoying the Z at several race events:

“So many of the remaining pieces along with the 1971 championship motor is on display at my shop. After going to a few shows with John Morton in the car I told him I wanted to race it and he kind of smirked and said it’s a show car not a race car and my reply was we’re gonna race it will you drive it and he Sylvia was nonchalant and said yeah maybe… when we signed up and got into the first Rolex reunion in 2017 Rolex Monterey Motorsports Reunion.”

 

“John wasn’t really excited about racing the car Rob and I could see that even when he got belted in the car. When he came back after 6 to 8 laps a different man had returned he immediately walked over to Sylvia and said what are my times – He knew he was turning really fast laps and was getting really fired up! He told Brock down at the Carmel car show that the show car was truly a fast racecar! That weekend he terrorized all kinds of Porsches including 935s and was running up front in the top 10 out of a group of 40 to 50 cars. This became really fun so we’ve done it now at Road Atlanta Laguna Seca and now Daytona!”

 

Big thanks to Randy Jaffe, Sylvia and John Morton, the ZCG team Josh and Keith Corwin, Meghan Fuller, Michael Eberhardt and Vintage Racing Company and HSR this was a memorable event we can’t wait to come back to next year. More pictures in the gallery below:

LONG LIVE THE Z!
