Hey Guys, I'll try and keep this as short as possible. I've had my build going together for a while now. It's a 557 cube (4.5 x 4.375) Bill Mitchell block with port Indy EZ's. The motor is in the car is running well and my pro parts headers just arrived this week. So, I'll be headed to the track soon. Anyways the plan for this build was to upgrade the heads in a year or two knowing my EZ's are too small for the cubes. Well as luck would have it a deal came along now.... So, I bought a set of fully ported -1's flowing just under 400cfm. They will go on over this winter. Now... the fellow that found me the heads also has a couple 440-3 intakes. He feels one would work good on a motor of my size. Indy recommends this for much bigger engines. Thoughts? I currently run the 440-2.
