With everything being the same the 5.4 will make more power due to the increase in C.I's. You guys just don't get it.........
BTW, that's the weekest 5.4 3 valve I've seen. Most around here make around 235RWH.P.

5.4is still weak... lol and u make excuses saying change the cams and intake manifold so on forth but the whole point is comparing motor for motor even the 294hp version thats in the explorer. but increased displacement only helps if u have the heads to help the flow and the intake to support it.. since since the 5.4 doesnt then yeh it sux

are you talking about this
i read that as he has a stock blower, no mention of the heads and cams. if i missed it can you post were he talks about having stock, unported head and cams
since you are posting on that board ask the guy if he has head work and different cams
Haha that's 351cu.in but my 324cu.in with 100% stock 03'cobra SC made 510rwhp and 560rwtq at 2,800-4,000rpm(almost flat tq curve) at 10psi! total timming 15* My car almost made as same as rwtq GT500 with 2.8KB 24psi!

Patman and paul's numbers tell the story,
Neal's just getting grumpy cause I could pull next to him and smoke in my Scab with a full tank of gas
Just kidding, at first this thread started out in jest, I thought I was in a motor oil thread for a second
Now, can we settle down, be stupid boys again and have a silly "mine's better than yours" thread

ok when comparing truck v8's take the f-150 v8 not the mustangs or the explorer's v8's they are completely different motors they rev higher and they dont have a stamp anywhere signifying TRITON on them the 4.6l f-150 makes 231hp stock i belive ant the 5.4l makes 260. fyi just because ford makes a 4.6l doesnt mean its the same v8 and yes the explorer runs the mustang v8 and not the truck v8
