Why do some heads list multiple hp for the same ci engine?
Ex: 1968 62 heads, lists hps of: 330,335,350,360...with the AT.
Other then cam, carb, or if its ram air, is there something else thats affecting the hp?
If I have the 9790071 400 block, 62 heads, stock intake (9794234) & Qjet, AT, what can I expect for hp? The Firebirds listed 330 for that type of setup, so is that what I would assume for ending hp?
..hm..what was the standard 400-4v heads for an Oct 68, 69 model Firebird? Wasnt it the 62 heads? ..or were they 16s, or something else?..
