1970 Nova - Owned by Mark Rapp

1970 Nova - Owned by Mark & Teri Rapp

Car Of The Month for August is this sharp 70 Nova that belongs to Mark and Teri Rapp, aka, Mark70nova on the Motorsports Village Forums.

Mark took this all original one owner seafoam green Nova, that was barely driveable, and turned it into a screaming beast. The car was built in Mark’s garage at home. The Body was in quite good condition when Mark bought it but he did replace the front fenders with aftermarket steel items. The 4 inch glass cowl hood, glass deck lid and glass bumpers replaced those steel parts then everything was prepared for painting. Mark describes the paint job as a “cheap Macco Tornado Red" that has been "rubbed and rubbed" to the point that looks pretty good on the track.

Mark’s Nova is powered by a strong running 383CID SBC fed by a 750 Holley sitting atop an Edelbrock Super Victor intake. That intake sits on a set of “out of the box” AFR220 heads. The short block is filled with a Cola 4340 crank, Scat “H” beam rods and is topped off with a set of SRP forged 13.2 to 1 compression pistons. An MSD billet distributor, MSD crank trigger and Crane HI-6 ignition provide the spark to light the fuel mix off.

Putting the power to the rear end is a B&M shifted Tim Deal Turbo 400 with full manual valve body and a transbrake. An 8 inch Hughes converter connects the transmission to the engine. A Denny's Driveshaft transmits the power to the 12 bolt rear end with 4.88:1 gears. Mark has installed Cal Trac's and Calvert split mono leaf springs that he reports as working exceptionally well and contributed to his hard leaving wheels up launches. Wheels are Weld Draglites all the way round with Mickey Thompson tires.

Inside is a Chrome Moly cage built by Fast Eddies Race Cars. RCI belts and a Jaz seat completes the safety equipment. Also inside are Autometer gauges and a Data Logger.

Mark has finished in the top 5 in the Open Comp and Mean Street categories every year since he completed the car, winning the Mean Street class in 2006. The car runs 10.1's @ 132.5 and has recorded passes in the low 6.30's at the local 1/8th mile track. Mark says he spends a lot of time trying to slow the car down so he can run it in the 10.60 class so he doesn’t know exactly how quick is could be. Maybe one day he will find that out. I’ll bet there is a good bit still in it!

Mark says were it not for his darling wife Teri, probably none of this would have happened. She is very supportive, loves racing and also works the tower at every PSCA race they go to.

Currently Mark is 5th in the Mean Street class and is hoping to move up to be champion again this year. We wish him luck as he tries to win that championship again!
