Nice power, but the torque is a little soft. I would expect the torque to be in the 480-490 range on an engine dyno when optimized. Should haul *** though. Well done.

No disrespect, but the numbers are low. TQ for that motor should be close to
if not over 500ft-lb, ask Patrick if you don't want me saying that, and with that being the case, if it is something fixable - IE bringing the compression up, cam timing, ignition timing, port transition issues, your power will be well over 600HP but under 700HP, again, ask Patrick if you just don't want to hear it from me.

I don't mind constructive criticism(sp?). I know the Compression ratio is low. that is intentional, street driver, 91 octane. Port velocity is probably low considering the size of the heads. 242cc intake. I will probably go EFI early next year and then Turbo(s) the year after that.
