   I HATE TO SAY BUT i think monzter is right about that kind of idea. for me as my self in my chevy camaro i might would just rebuilt it, it could be something else went wrong like camshaft, pistions etc. in motor is not right size to fit.

   Well I proved my theory on Demon carbs on Steve's 355 at the dyno. It picked up the HP quite a bit and he was so convinced he bought one for his motor. I used the one off my Green Monza which was an 850 cfm Mighty Demon with annular discharge nozzles. I did not change any jetting from pulling it off my car but I did put the rest of the parts back to the way I received it when I bought it new. Like I said it helped Steve's motor a lot with a pick up of something like 17 HP just by bolting it on. No jet changes were made or tuning with it either. He originally was using a Quick Fuel Technologies 750 cfm carb that was around $750 with all the air bleeds etc... We did try to tune his carb in but it was not liking it at all. My carb was something like $549.
   
   LIke I said if you want I can run my program to see what it does. Just an idea !!

   I wouldn't think that a 750 would be too big of a carb on this setup. I would recommend putting a kit in the car (Quick Fuel Technology ) and upping that powervalve to an 8.5 or even a 10.5 depending on your camshaft. After checking vacum reading at idle with the car in gear of course to be sure. You'll find that choosing a PV with a reading of about 1.5 lower than the vacum your pulling is best. Say you have 12" at idel/in gear...a 10.5 would be the way to go.
