Best Throttle Body For Gt350 Intake?

FYI, the 87 mm GT 350 throttle body has a different bolt pattern compared to the stock 80 mm or the aftermarket 85 and 90 mm units. I tried to do the stage 2 upgrade the cheap way by just getting the 87 mm TB and a tune and every tuner I tried could not get it to run right. You might want to try one of the power packs from ford racing. Blowfish racing makes an adapter plate to bolt the standard pattern TB's (80mm, 85, and 90mm) to the GT 350 manifold.

Stock TB with the blowfish adapter is the best.
I am planning out my install here very shortly and ordering the bits and pieces slowly.
