Thanks for the info. I'm still talking to them and tonight they told me of their new 730 cfm gas blow through carb built to the specs I provided would be $890.00 plus $16.00 shipping. Not outrageous, but not chump change either. They also told me that based on all the specs I gave them on this stroked and blown motor, that their computer program indicated I could expect 550 HP out of this motor I'll believe that when I'm standing ouside the dyno booth and reading the printout.

I have done some studies on there single venturi carb and it looks pretty good. I know of a few who have run pro system carbs and were pleased with there performance. These were all N/A applications so no advise on the blow thru but the fit and finish look good and the two I know of are enough for me to try one on my next engine.

Anyone have any experience dealing with Pro Systems Racing Carbs? You fill out a spec sheet with all the variables on your engine, trans car weight ect and they build the carb to your needs. Their cost to custom set-up one of their carbs seems to be less than buying a Holley HP double pumper than having to modify it for blow through application.
