A friend of mine is looking at a tri power set up using a 318 wide block intake manifold on an old 500 cu. motor he is building. He is doing some modifications but wanted to know if anyone could help with some measurements regarding this type of manifold. The question is the ports appear to be symmetrical but how close are the ports center to center measurement wise between the 318 wide block and a 500 block? Or is it even feasible?
Thanks.
