Small Block Head Flow Chart

B3422w5 said

based on everything I have been told about the moved center head, and the several I have seen results of in running combinations, I tend to believe everything people have said about them over the years.
Bad design, underachiever. I don’t think they are as good as a w5 head, then nothing fits them either

Thats what I have heard too. Brett tells me that his program is in W8-W9 territory. Plus the casting itself is really good even though the deck on it isn't all that thick the casting is very strong and is well suited to boosted or nitrous applications. He has a customer that has made 940 with a set on the motor and over 1400 with one kit of nitrous. By the way it outflows my W5 by almost 40 cfm and my W5 is no slouch.
