No I was thinking of using a small cubic inch engine thinking that maybe the shorter strokes will help it wind up quickly for the 1/8 mile. I just havent had a chance to research it thoroughly. 283,327 might work in a light car on the 1/8 mile. Like I have said though I havent had a chance to really look into it, but by comments I have read here all ready it seems everyone thinks they are a waste, dont know??
