[QUOTE="01yellercobra, post: 16143773, member: 35549"] I think this might be the one time I disagree with you. I would stick with the 4V set up personally. The money he'd put into swapping to a 2V head he could invest in porting his current heads. You also can't compare a 5.4 directly to the 4.6. The displacement makes a huge difference. My 5.3 made 326rwhp, but it had stock 04 heads, stock 01 intake, GT cams, and "low" compression. If I had built that engine as an N/A set up I'm sure 400rwhp wouldn't have been a problem. But that wasn't the goal. FWIW, I did know a guy with 5.3 and FRPP 3V heads that made 435rwp I believe. But it was a 12:1 engine on E85. Just have to go with what you want. OP, is your budget 10k or is that just where you ended up? [/QUOTE]
