With '87 and up intake manifolds, you have to be concerned about whether the manifold has a Vortec-style bolt pattern. If you have iron heads, manifolds that are pre-'87 style will fit. Regarding the choice of intake, it is six or one-half dozen to the other. You will find people that swear by either. One person on another board claimed the Team G had better quality castings and a smaller plenum for better street performance. The Victor Jr seems to be used a lot in testing and was recommended to me by the forum supervisor. Since you should port match any manifold, the supposed mismatch on the Victor Jr would not be an issue and could simply be an isolated example. But it should outperform the Team G at high rpms given the larger plenum. I could not find an internet hit for a dyno comparison of these two manifolds. I think either should do the job for you.
