Quote: First of all where talking about the 383 here , not the 440 in that test - Also the Performer WASNT in that test you posted - Also in that test the Performer Rpm makes a positive torque difference down low compared
Again 383 , and the Performer wasn't in that test

Who is we ? Maybe you need to re-read the question....it clearly asks about a CH4B and whether or not it will fit on a low-deck. Of course the answer is no.
You go on to inject your opinion on the CH4B which is indeed.... wrong. There is a huge difference between a 440 performer and the CH4b. The 440 performer is more restrictive than a stock manifold....on a 440 with some cam/headers it's all done at 5300 or thereabouts. I know i had one on my old 446 !
The 383 performer is a much better manifold vs it's 440 counterpart, that much is obvious by the dyno results and a visual inspection.....no disagreement there. But saying that the CH4B is no better than a 440 Performer is Bull$hit.
