Throttle Body:
So i just had Mancuso Crossroads install a stage II kit on my 24 RG (511 cam/high cap lifters) and i was already running stock exhaust with Rinehart 4.5 slip-on's and wedge air cleaner. It gives me nice gains but like all of us, more is always better. A buddy told me i would also benefit from a bigger throttle body. I'm not Bill Gates, so i want to maintain my warranty, and it looks like Harley sells a 68mm throttle body and accompanying manifold. Will it bring me more HP/TQ or is it too big for my stock heads? Anyone know for sure?
