On my PC, I have made a Word program telling some history about the car and what has been done to the car. Including brands of parts and part numbers. It is six printed pages long. This is great information and will save guesswork for the next owner.
Best 1/4 mile run - Beech Bend NHRA National Open 5/27/23 10.473@125.38
Best 1/8 mile run - Ohio Valley Stock/SS combo 10/26/24 6.527@102.31
I was only able to race this car three times in 2024, because of health reasons. All three times were at Ohio Valley.
$50,000
The suspension components are the same as any 68-72 GM A body. Also, uses a GM (Chevrolet) 12 bolt rear end and TH200 transmission. The firing order is 18436572, so valve adjustment would be familiar to most racers, and uses a Quadrajet carb.
Call 270-234-4259, if no answer, please leave a message. 8am-8pm EST
PM and texts, OK
Thanks,John
