I always wanted to fix the core support on that thing, but John wouldn't let me.
Couple of questions/errors I saw for clarification...
-Car runs a Hurst prepped, Bowler rebuilt TKO 600
-Tires are 275/35/18's front; 295/40/18's rear on stock sheet metal
-Last dyno the engine made a whopping 304rwhp. A bit too much cam on the last rebuild unfortunately.
The car REALLY showcases the ability of our cars with these suspensions and the futility of all the coilover/rack setups. Last few Carlisle events one of the fastest cars was running a mildly built /6! I really dug that car. Some of our competitors cars came to play; even with big tires, big power and a talented driver; they couldn't get it together. Some of them that we know are regularly raced just sat on the show field <shrug>
Mufflers are flowmasters with a nascar-style tip welded to the sides of the cans for side exit and the factory hole on the muffler capped. The boom Tubes were being crushed between the SFC and "debris" (cones) from time to time.
