I ripped a set of Trick Flows off, for waaay better flowing Eddie's(ported by a genius. And flowed.) If the AFR are a China casting, I'd stick with Edelbrock.
Just watch Eric's YouTube video flowing the TF's. They did NOT flow as advertised. I doubt the AFR' do. Weak as their numbers are......
I've been down the head rabbit hole, probably farther than most. Nothing other than ported W2's or something exotic has come close to my OLDER Edelbrock castings.
I think if good old Pittsburgh Racer were here, he might agree.
