Supercharged Smallblock Combination.

I'm thinking you wont see 700 hp with that combo. Not enough in there for what the blower will draw to make it. I would also scrap the iron heads..10psi isnt enought o pass that kind of air thru those small ports. Also, an air gap is worthless..The blower will be making power, you'll just be generating a lot of heat in taht dual plane. I klnow you already ordered it, but I would have gone turbo. Much less parasitic draw from the engine, and easier on things like the crank. That's a huge load on the snout. Bowers were cool, but turbos are the way to run and make the big #s now.

I am trying to follow you but I'm not sure if I am getting exactly what you are saying. 10psi on that blower should be plenty for a starting point to tune from. 750hp seems high, I agree. However that is the estimated ballpark for the combination.
Worked cast iron heads seem to be doing pretty good when paired with a supercharger.. http://www.thesuperchargerstore.com/martyfox.html

After reading a few comparo's again on the Airgap intake (granted, none on F/i cars) they were within 5hp of the single planes. In my mind I would rather take the extra mid-range than the 5-10hp at peak.
This is not going to be a drag only car. In fact the suspension set-up is going to be geared for road course/better handling.
I whole heartedly agree with you on the turbo thing. Turbo's are "free" hp. However, to even think about getting one in my car the fenderwells would have to go, then all the tubing, plumbing, wastegates, etc. Then to make the big numbers and be somewhat street usable I would have to go with twins. On top of all that one of my close friends is doing a turbocharged dart sport....I can't copy him. lol
