A friend of mine has a motor for sale, a 454 that puts out 788 dynoed hp. Heres my question I asked him what it had and what he told me just didnt make sense. Can this happen.
19?? 454 block, stock crank polished, hyper 10-1 comp pistons, gm bowtie heads rectangular port with angle job and bigger valves. Dont know angle and size of valves. No head work. Pretty much stock head. Crane cam, dont know spec. but he said its mild. Single plane intake. Single 850cfm carb that was jetted. Ohh yea the blocks been preped
He told me it has 1 pass on the dyno and thats it and it made 788 hp. The reason I ask is my buddy hydroman916 has a well fully built 454 that puts out 654hp on the dyno. Hydros engine builder says its possible. Hydroman says only one way to find out, to take it dynoed. cost $$$
Can anyone shed some light... I know theres some guesstimating because of unknown of heads and cam. By the way he wants 1900 and has 6k into it.
