Hp and tq guess?

I just finished my first build. Can anybody ball park up horsepower and tourqe for me?
Is a sbc 350 bored .040 over.
Dart iron eagle heads, 175 cfm intake runners.
67cc chambers.
9.8 compression.
Zero deck with +7cc flat top piston
.039 head gasket.
Performer intake with 600 cfm carb.
Long tube headers and 2.5in dual exhaust.
[email protected] duration at .470 .470 lift hydro flat tapped cam. 108 lsa
I'm going to try to get this on the dyno before I swap motors. I just want to see how close the computers calculate it.
Thanks?

Do you have any 0-60 or 1/4 mile numbers?

Mine is a similar set up but I can only guess at 325-375 hp. Never been on a Dyno., so I guess my guess is worthless.

Not sure it's worthless Gary, 325-350 is what I was thinking. I like the 0.039" squish/quench, but not the flat tappet cam.

Same here, I'd think 330-340-ish HP.....

"My bid on this showcase is 338 Hp , Bob"

(that's flywheel, not chassis dyno)

I'm going to be a little optimistic and assume that the 175 cfm is supposed to be 175 cc and I'd guess 360-370 hp and 380-420 ft/lb torque

There are a lot of variables that affect this but if your 0-60 is around 5.5 seconds I say 335 hp, if you are closer to 5.1 seconds then you are closer to that 360 number.
Just guessing.
