chevys don't have valley pans
first let me say that this is my first pontiac-a basket case of a 67 gto. but it appears to be a numbers matching car. i just have to put it back together!-well not quite that easy...anyway i need some info on the valley pan. the engine is a ys code and the valley pan that was in one of the 8 boxes of stuff has a pcv opening towards the back of the engine-right side. when looking for another one some tell me it should be in the front. i'm collecting some parts for the rebuild and would like to get the right one. which should it be? pics anyone? thanks.
