Questions about SBC 350 build up

[jcloud6]

I just finished putting my 350 back together, but don't have access to a dyno. Based on this information, and your experience can any anyone give me a ball park figure of how much horse power the engine is going produce.

1970 350 4-bolt main stock block bore 0.30 over
Flat top pistions
Compression 10.5:1
Vortec Heads casting #12558062 (stock)
Comp Thumpr cam CS 279T H-107 Duration @.006 tappet lift 279/297 Gross valve Lift 479/465
power range (2000-5800)
Edelbrock Vortec High Rise Air gap Intake P/N 7516 power range (1500-6500)
Street Avenger Holley 670 cfm carb
Accel performance distributor w/ HEI super coil

Thanks for any feedback or recommendations you can provide

Probably in the 375 to 400 HP neighborhood. Just my guess...

I'd say 25 less then above estimate...350-360.

That'd be my guess also. Probably right about 350hp.

Comp cams has a cam selector tool. You can enter your info and itll give you its best estimate.

Headers?

[jcloud6]

Thanks guys for the feedback, that's information I was looking for. To gain a few more horse power, It has been suggested that I port match the vortec 062 heads and select a different cam that will work in sync with other components. I failed to mention the 1-1/2 tube header in the initial thread.

I have a real close setup to this,similar cam numbers, same carb, 882 heads which dropped my compression I'd think and a weiand open plenum. I port matched intake and exhaust and we're going with 350hp
