yeah but 8 psi on a 4.6 and 8 psi on a 5.0 is going to be different. thats why i added the higher displacement has more potential.

I think they make more power in terms of what you get with FI on a modular compared to what it does on a pushrod. It may be that the modulars are rated higher to begin with and that clouds the final numbers, with a 260 or 300fwhp 4.6 compared to a 215 or 225 5.0 the numbers are obvioulsy going to be higher on the mod. I think the air flow is better on the modulars too and that plays a part in power production too with FI.phil_the_thrill said:what do you mean in your opinion? like in your opinion they make more power or in your opinion they last longer or what?
phil_the_thrill said:so your saying that if you have your heads ported to the best possible flow rates for a 4.6, get the most aggressive custom ground blower cam and run it at 8 psi, it will make more power than a 5.0 with ported heads, cam and 8 psi?
phil_the_thrill said:well if youre willing to bet your life on it i guess ill have to take your word for it but i never wouldve gussed it.
phil_the_thrill said:i didnt really take into account that a 4V will always outflow the 5.0s. my arguement was based on them having similar flow rates

Pushrods and displacement will continue to make more power for less money than the tiny-bore-plagued OHC Ford architecture.
Oh, and all hail the LSx.

Finally, someone who knows what they're talking about.
LSx > 5.0 > 4.6
thats some high tech, top secret type stuff 8)phil_the_thrill said:actually the future is an engine with valves operated electronically by actuators 8)
