    I get something like 370 HP at 5,000 rpm, 426 lb-ft torque at 3,500 rpm. Not enough difference to spit at between the cams. Run the hydraulic.

    Heads are the right size along with the carb.
    Good intake.
    Overall very well matched.
    The only thing I see is the comp. ratio.
    The .488/.510 has a 234/244 at .050.With this cam you really need 10 to1 as a comp. ratio I.M.O.
    With the 9 to 1 comp. ratio I would try this one .465/.488 duration at .050 224/234.

    If your heads flow good numbers and everything else is matched intake,carb, etc. it is enough cam to make 1 hp per cubic inch.

    I agree with Erik, run the cam that he recomended along with the Air gap intake. You should make somewhere around 370 horses with that combination. Don't run a torker intake, the torker II's are alright.
