What I am thinking is that the intake must get all the heat it needs from the fenton headers, to do the offy manifold on a 235 you have to grind it to fit the fenton headers and end up really close to them. With water heat the engine must have to heat up first to be effective and then your at 160 degrees The headers are alot hotter and heat up sooner.I have not run this combination yet but do have it set up on a rebuilt 235 setting on a 49 chev 1/2 ton frame and i am very intersted in hearing comments from anyone who has been there and done it.
