82 intake porting
I'm new here and haven't had time to check out the 5 thousand pages of tech articles. I have an 82, basically stock and I was wondering if it would make a difference on the positive side to open up the intake manifold. I know it has castings that cover up half of the intake ports. Would it be worth my wile to grind these down to gain some performance? Thanks in advance for the help.

hoss,
Your '82 was fitted with a twin throttle body fuel injection system. The stock manifold is probably the worst one ever fitted to a small block Chev. I read recently of an aftermarket manifold with much larger ports and you might be better off buying one of these and having your TBI units reco'd rather than hand porting a sub standard manifold.

not a crossram, just a weiand x-cerlator w/ restrictive box on top. 17HP gain on original engine w/ low rpm torque loss, same gain w/ ported manifold but no tq loss
