Well i'm brand new to the forum thing and the Big Block too. I recently bought an 85 chevy stepside with a 402 BBC. Now the guy i bought it from said it's a straight 402 and not a 396 bored out. I havent a clue about it. He also said the tranny is a 700R and it has a posi rear end. Thats about all i know about it. Anything anyone can say would be greatly appreciated. Thanks!!
