Getting ready for a fresh build this winter, I have the engine pretty much planned out but I am open to suggestion. Stroking isnt an option right now or this would be a 545.

468-472ci (depending on how the cylinder walls look when we tear it down)
12:1 comp flat top pistons
stock stroke, 6.605 H beam rods
TFS Street heads, 74cc fully ported
Victor intake
1050 dommy, fully race prepped
comp 34-711-9 solid roller
scorpion roller rockers

Looking for a few HP and TQ estimates, as to what I should expect with this engine. Its strictly mud race, no street driving so any other tips and tricks are welcome.

HP & TQ

Mudfreak,
I ran it through Desktop Dyno and it says peak torque around 6000 rpm 575ft/lbs and peak hp around 7000 rpm 715hp. I used some posted flow rates for the Scotty J spec'd TFS street head flow numbers. Some others may chime in with actual dyno numbers.

FWIW Mark L.
