GM Performance Parts Aluminum Vortec Intake Manifold
I think this is the part # 809-12366573. Is anyone using this with their TBI? Do you need a 4 brl adapter plate? Did you feel it was a good performance gain or would you recommend something else. I am running a 355ci and would like to upgrade the manifold next. I'm looking for something that won't run out of steam at high rpm.
Thanks in advance,
GC

New Albany off of 161.
What do you think of your SLP's?
I will do headers before a manifold.
