LT1 Intake Manifold porting...
Hey everyone,
I just recieved a ported intake manifold that I bought on E-Bay. The listing said that it was a fully ported manifold that was matched to a 58mm throttle body. Measurning the manifold, the TB openings are anywhere from 48mm-55mm & the holes arent even round. Looks like he opened them up with a hand tool. I have never used or purchased a ported manifold before. I am thinking that the piece I got is a hack job, but I want to make sure that this isnt normal before I start complaining.
Thanks,
Mark B
