I figured that with "Uncle Tony" tuning, there could be 50 extra HP there.
I said 690 to 750 hp, where as others were guessing in the 800 HP+ range Like I said, the compression ratio bothered me. PROBIRD missed the RPM as did I, as I thought it also would be in the 6500 range. Still a 700 plus horsepower engine with low compression at only 468 CID is a strong Pontiac engine. I think the best that Marty P ever got NA was 735 hp with a 473 engine so you are in good company. Yep, PROBIRD gets the "honey baked ham" on this dyno guess contest. Tom Vaught

Sounds like a good solid build that will last with little maintenance.

Congrats Brad!
Once you get it in the car we can review you info and do a final tune for the street. That way you can drop down on your primary jet size and go back to using a PV...providing you have vacuum. Do you know what the engine had for vacuum at idle?
