Right now I have Beck sheet metal intake with a forward facing 105. I was thinking of going with a new top and an Accel 4500 throttle body. Ive been told this will make more power. Just wanted to know if anyone has had any experience doing so. Is the 4500 the way to go? Motor is a 454 LSX block, 245 Trick Flows (done by TEA), Bullet Solid roller, 12.5 comp, Beck intake with Nitro Dave dual stage plate system.
