I'd run a proform main body with your 750, it will flow much better (823cfm) I'd also send you carb to SDCE and have Scott boost prep it. I gave him mine and the specs of the engine/car and he did a bang up job... you should have way more hp than mine but my old set-up was a .030 over 9ish:1 440, with stock replacement cast pistons, Summit 488 cam, 906 heads, RPM intake 750 DP w/ proform main body, SN-2000 w/ modifed impeller, 1 3/4 headers, 727, 175 convert (2800) and 3.91's (3.55's would have been better) car went from 12.90's (good day) to 12.0's. Swapped to a different pulley for more boost but never ran it.

Depending on boost ,bob weight and rpm, bloc life may suffer. One thing that will seriously help the situation is a center weighted crank. It spreads the stress back to where it comes from, taking some of the load off of number two and four bearings and spreading it to the others. I mention this because most of us get greedy for power, and with a forced induction, you can go too far easily with the right setup. You should use after market main caps for sure. I like aluminum, to lower the shock loads. Other guys go with steel, for other reasons.

What are different benefits between ALuminum and Steel billet caps? What a stud girdle? I would think those would help with the cap walk more than caps?
Alum. will absorb some of the shock load , the best system is the BRC caps and girdle , contact member Jerry , he has taken over making them from Greg/BRC.
