Re: why is my 347 making only 400hp help me
ive hit in-accuracies with dynos before a few times. Does it feel like its got 450hp or is it lacking?
my 302 makes 246rwkw, which is about 460hp from memory admittedly its probly more worked than your 347, but still you should be near that figure....my cam is 597' lift and i use a barry grant 650dp demon. it has 4 into one tuned length headers and a dual 3" system.
what sort of ignition are you using? what plugs and fuel are you running? running thermos or the huge ass belt fan? (that is a true 10hp gain)
