I paddocked with Ed Forrest at Road Atlanta last labor day, he drives the red, white and blue AMC Spirit. I drive a TR8 -- we called our spot Team Oddball.
That car was really cool, the Spirit. It has I believe the biggest engine in IT (bigger than my V8) - a 4.2 (I think) in line 6 truck motor. Redline is like 5,000 rpm or something. He has fun with the car, and I liked its look.
The Yugo was I believe Al Matthews' car. Still has the ITD record at VIR. Didn't know he killed it at Kershaw, that's a shame.
There are a few TR8s, TR7s, Opel GTs, Alfas, etc. out there in IT still. About the only car on the spec list I've never seen run, or heard about running, is the Jensen-Healey in ITS. And you know, the damn thing would probably make an OK ITS car. It's the Lotus 907 engine, at 140 hp stock, and probably capable of near 170 or 180 in IT trim. And the car is light as hell, 2100 lbs. I believe.
I do love the oddballs. Maybe I need to add a Jensen-Healey to my fleet...lol.....
