All these parts are what is currently on the car. Performance results may be from previous configurations.



  • Complete wiper assembly and related parts removed.
  • Both bumpers and related parts removed. They can't be seen behind the plastic covers anyway.
  • Manual steering box from an 87 S-10 pickup.
  • No interior except an aluminum dash and a race bucket seat.
  • Non tilt steering column is stripped down to just a shaft.
  • Manual brake master cylinder converted from an S-10
  • Full roll cage SFI 8.50 certification
  • 5 point harness and window net
  • Race weight for 2011 is 3030 pounds
  • Lexan locking T-tops from a Formula Firebird. Undersides painted black to keep the sun off my head.
  • Lexan windows all around.
  • Lexan headlight covers
  • Sheet of aluminum made into a simple deck lid and secured with Dzus fasteners
  • Custom made rear wing
  • All IROC body ground effects still installed.
  • Working tail lights and headlights remain for night time racing. All other non essential wiring removed.
  • Mirrors and antenna removed and the holes have been filled in.
  • '82 fiberglass hood with a 2-1/2" cowl scoop. A Hilborn style scoop pokes out the top.
  • VFN Fiberglass doors
  • Hood latch, related parts and brackets removed. Hood pins now hold the hood down at the front. Factory hinges and struts still lift the hood. The hood is too big and still too heavy to be a complete one person lift off while in the pits.
  • Tranny tunnel has been cut out and refabricated to allow more room around the bellhousing. It makes pulling the tranny easier. A completely removable tunnel would be even better.

Engine 383 small block 1999-2000
(Totally destroyed during last race of 2000 season. Very few parts could be reused)
I found out from the previous owner that this engine had a lot of miles on it as a 383. It was in a Jag and a MG before being dropped into the IROC. I managed around 200 1/4 mile passes in 2 years before it finally let go. I can't really complain about how well it ran when I had it. This is what I had in the engine when it finally let go. These specs are just for referral purposes to show what can be done with a 383

Best results before the 383 blew up
Best ET on a time slip: 11.857 altitude corrected to 11.163
Best MPH on a time slip: 117.87 altitude corrected to 126.10
Altitude corrected rear wheel HP based on power to weight ratio: 476.5
Best 60 foot: 1.662
