what do you guys think im leaving on the table staying with the 750? I ain't a drag racer but the Q reminded me of a statement by my advanced tune up instructor way back who stated that if you have over 1" of vac at WOT then the carb is too small (too much restriction at the venturis)

Brad, i got a quote from prosystems, he suggested a 950 with his blocks ect. i might go that way. he mentioned gains that seemed like alot to me. am i leaving 25-30 hp on the table with what i have? or am i leaving 5-10? i guess thats what im wondering. Is PJ saying his "950" is worth 25+ HP over your current carb? Seems like a he11uva lot... but I don't build & sell carbs for a living.

If you are going to buy a carb, and then start changing it around, can I suggest you talk to ThumperDart first. He can modify an out of the box piece or build you a whole custom carb for your combo. He's a straight shooter and knows his stuff.
