I ran an '86 Pontiac 6000 in one. I placed 5th of 16 cars in my heat race. I missed the feature by 1 spot. My neck was a bit sore for a couple days. I'd do it again if the rules were to allow a plastic boat tank in the place of a steel one for the F.I. cars. I'll never run in a fullsize class, though. Those boys hit a lot harder than the guys with a midsize.
In a while, Chet.
