Head gasket bore and thickness, Piston down bore @ TDC

I'm showing 380 HP @ 5000 RPM, Great low end torgue

I think I got every thing in correctly, I'm new to the Dyno Program.

Micheal,, which new program do you have??

dyno 2000

Your 355 should be makin around 425-450hp.
Some bowl work and a DP carb would help a bit.

Head gasket bore and thickness, Piston down bore @ TDC

Thanks guys! Head gasket bore is 4.130 with .038 compressed thickness. Block has been zero decked. I do plan on using a Holley 650DP this spring or I was going to buy a Quick Fuel 650 DP, but not sure about Quick Fuel.

I just got the ProSim Desktop Dyno and then upgraded to the Protools version. Still learning. Its an upgrade for me from the Motion Desktop series. Lots to learn here.

Well I ran these numbers on Motion Desktop and new DynoSim 4.20, Motion shows just HP, the DynoSim show flywheel hp/ tq. @ 5000 rpm, 421 x 442, 5500, 451 x 430, 6000, 469x 411 & 6500, 475 x 384.

Now tell me how far off,, I used the LUN solid cam you listed

Lets see if their is a diffrence in the programs?

@5000 rpm 452 Torque 432

There are so many ways to come up with diffrent numbers.

Wow, I'm pretty happy with anything over 400! :D I'd like to get it on the chassis dyno this spring and see how the rear wheel HP corresponds to the sim programs.

Thanks again for all your work guys.
