Post Horsepower estimate

my buddy has a 350 and he is wondering how much horsepower he has from what i know the motor has:
750 Carter carb
Victor Jr. intake "with 2 inch spacer car"
993 heads 1.94/1.50 valves 3 angle valve job
Crane Roller rockers
Crane Engizer camshaft " 282 duration, .470 lift 106 degree lobe seperation"
hooker headers
Flat top pistons
9.5:1 compression
and the heads are 76cc chambers and 170cc runners
someone built a motor almost identical to it and it dynoed 375 horse on a dyno, does this seem right? or in the ballpark

Desktop Dyno shows 329 horses at 5500 RPM. 352 ft. lbs. of toque at 4500 RPM. the dyno shows if it`s for a street machine, a dual plane intake would be beneficial. keep in mind this is only a ball park figure.

Desktop monte said 350hp after a 6pack of 16oz Icehouses,now theres reliability you can count on.
Really though a Performer RPM would prolly be a better choice for a street car or heavier car.Like said above and would also match those heads and cam a little better.
The Victor would be good for like a Drag car or really light car were no lowend is needed.

I would agree with others at 350 HP as is, but with some good pocket porting on those heads, the 375 is right on. I have a set of 993's on a 406 that I hand ported. Made a big difference.
Easily worth 25 HP.

give me a guess too?

I have a 350 bored and stroked to 383. Forged pistons and rods. Edlebrock performer rpm heads, edlebrock performer rpm intake manifold and cam. I think the cam is 234 @.50 on intake. I have 1 5/8 inch hooker headers and 2 1/2 inch true duals out the back. The edelbrock performer series 750 CFM carb and an oil pan with a windage tray and scraper. Compression is at about 9.6:1. All stuffed into a 1973 vette.
Any guesses?
Thanks..
Tank.

Thacolbster, I would say you would be running around 360-375 in the 4500 rpm range
