Need help and advice (Intake and carb swap)

Hi. All excellent advice from rumblefish360. I just have one thing to add. There are two dowel pins one in front center and one in the rear center in the block where the intake sits. Alot of aftermarket intakes do not have the holes drilled underneath for those pins,so you can either take out the pins or drill the holes in your manifold. Just use the front and rear pieces of your gasket as a template to mark the spot to drill. You may have already found this out depending how far you are with the swap. Good luck. Bobby
