I know Im going to get in trouble for this but.... read this article, but more importantly, towards the bottom of the reunion of the Grand Sports. I have seen 40% of those cars so far. The two cars in the back of the photo are the ones I have seen so far, and i have the pics to prove that Ive seen one of them and I taped the other. now the one im gonna show you is not supposed to be shown ot the public...but its been almost a year so here it is.
and heres its 377ci 550hp engine
the other one is on tape, I didnt take pics of it, and it wasent racing, noone races these anymore which pisses me off a little but w/e.
