Small Block & Big Block Chevy Specific - How much horsepower should this combo make???

This is my engine specs that will be going into the 67 camaro. Just wondering how much horsepower do you think this combo will throw down.
355 sbc
dart 200cc iron eagle heads.63cc chambers
10.6 compression
speed pro hyperutic pistons with teflon skirts
eagle cast crank
eagle sir i beam rods
solid comp cam 532/555 lift 106 lobe @ .50 250/260
Carb 750 holley
Wieland stealth intake

id guestimate around 425 area maybe more

I had almost this exact same combo, switch for a Victor Jr. intake and a Comp Hyd. .292 / .501 Magnum cam and made in the 425 range with Dart Sportsman 200's (the older version heads). This motor pushed my 3500 lb. Olds Cutlass to a best of 12.1's (consistant 12.3's) on the motor. I hit it with a 125hp NOS Powershot system and went 11.61@123mph with wheelspin. Be advised that with a Carb'd motor 10.6 compression is "borderline" for pump gas. I used to run Sunoco 94 with around 36 degrees of timing and when I had the heads "freshened up" they said it was boderline detonating and that I should either knock the timing back or mix in a little Cam II to raise the octane level.

I would agree.

I had a Vortec headed 383 with 10.5:1, and in the warm weather it wanted more octane. And that was at a very conservative 32* total.

i'd say switch to a rpm air gap since your motor should rarely see the high side of 6,500 rpms and expect around 450 hp.

I'd say the 425-450 hp should happen, but the stealth will definately cost you about 10-15 upper hp compared to a Victor Jr. The rest looks good, but you'll want to make sure to have a good stall (3400 or more) and rear gear combo to take advantage of the powerband (I'm guessing a 6600-6800 shift point). The compression ratio is borderline, and I'd sugesst also backing out the timing a little or mixing in a few gallons of race fuel with 93 premium to keep detonation out of the picture.

Good luck!
