445fe is done/thanks

The 445fe is fianlly done and going into the truck tomorrow. I want to thank all of you for the great information I have absorbed from this forum. Here is what I have in the motor:
Edelbrock 428 CJ heads
Holley 800 dp
Edelbrock water pump
Holley fuel pump
Hedman headers
RPM manifold
block was decked to .005
felpro head gasket
.046 quench
17cc dished forged diamond pistons
scat 4.25 crank/ i beam rods
modified oil passages for better flow for the high volume melding oil pump
clearenced valves to 74cc volume
matched manifold to heads
compression came out at 9.9
I am using a center force duel friction 12" clutch with a center force 428 fly wheel. The cam is a Oregon grind at 530 536 with 1.76 roller rockers; duration at .050 is 224 230/ at .006 it is 268/280; 112lda
I went with a performance hei type dissy...
What kind of hp and torque can I expect out of this motor?
Thanks again

Assuming that's a hydraulic lifter cam, it doesn't have any advance or retard ground into it, and you're installing it straight up:

418hp @ 5500rpm, 491ft-lbs @ 3500rpm.

I bet the torque curve is not much of a curve at all :-) Looks like a great truck motor.

In that case:

410hp @ 5000rpm, 501ft-lbs @ 3500rpm. That's right, you wont gain a thing over 5000rpm. Which I'd guess is exactly how you wanted it.

Sounds like quite the stump puller! That thing is also going to have a LOT of acceleration away from a stoplight if the tires are up for it...

And the torque "curve" is really quite flat. 483ft-lbs @ 2000rpm, and 473ft-lbs @ 4500rpm. It drops off quite sharply after that though.

Of course, this is all from Dyno 2000, and would be equivalent to a measurement at the flywheel.

I'm getting 418hp at 5500 RPM, 451 FT.TQ at 4000 RPM. Flat TQ curve. But some of my numbers might not be 100%, but it must be in the ball park.

Sound good.
