Contact @AndyF for his low deck manifold testing.
His Wilson ported 4500 low deck M1 made the best power in his stroker testings. 700+ hp.
Andy would have some good factual insight.
No argument on Andy`s stuff, and his knowledge , but $1500 to have Wilson manifolds work mine , ain`t in the books !! Wish it was, till my boat comes in I`ll have to do it myself ! LOL
