appreciate any input

For the street, RPM, for the strip, Victor Jr. That's a pretty small cam for 11:1 CR.

I have a Victor Jr. and run it on the street with my 383..I absolutely love it. That would be my recommendation.

I have close to that same combo in my 1980 Z28. the only diff is I use 200cc Iron Eagles. I use the Holley 300-36 Dual Plane. While I havnt tried anything else, I know that this is a big manifold and I have no complaints. Its a good piece.

Ditto the good old 300-36 intake, imho unless you want more "balls-out"??

Then go a single plane intake like already mentioned.

I'd go with the new Performer RPM Air Gap for best gains all over the RPM range. Use it with a good 1-inch thick (or more) 4-hole-to-open spacer (like those from HVH or Wilson) and you'll be vey pleased.
