LS2 motor in 2003 mustang... help

that was a 4 door sedan that was not anywhere near what that motor was capable of
How about you take from somebody who is building one of the LSX motors. Aftermarket heads on those motors flow 400+cfm can be stroked 511 cubes square. They are superior in almost every way from a racing standpoint. There is way to much internet racing going here. It takes a 18lbs of boost to get over 600 to the wheels on a mod motor, an LSX can make that NA...easy and hit over a 1000 with 10lbs or less. The difference here comes down to how much power your going to make on pump gas... Your talking modded to hell modulars that are not reliable and have to push 20lbs of boost to 800rwhp... the FORD GT, as bad as it is, itsnt that fast.... with a LSX instead of a 5.4 the GT would be like bugatti fast. Most of you just dont have experience building motors or being around bowtie stuff and there is just no comparison... as far as motor/power potential is concerned

If I thought the LSx engines were that much better than Ford's modulars, I wouldn't drive a Mustang. Yes they're good engines, but you're really just talking about the whole "no replacement for displacement" idea. What's wrong with boost? Boost on a V8 makes it crazy... look at a ZR1. It doesn't matter how you're getting power, it's the power to weight ratios (i.e. Lotus Elise.. 180hp? still manages 155 top end and sub 5-second 0-60mph times). Especially with a 5.4 or the new 6.2 Boss.. I think your argument will be outdated very soon.

Make no mistake LS motors are that much better. You drive a mustang because it looks good, is cheap and is a better quality car than the F-body camaros etc. Thats why I drive a mustang, but im not delusional. And it matters alot how you make the power, there is nothing wrong with boost... but when 1 motor is dying to 700 rwhp and the other makes 1500 with equivalent boost, there is just no agrument to be had for a moduler being better or even equal to an ls motor.

pretty sure the zr1 will blow the paint off of it @ 6lbs of boost, not mention the fact that the blower on the zr is not even needed, it will make power than it comes with n/a... but people want blowers now-a-days... but a zr is a pulley and a tune away from damn near 1000rwhp

i think ford builds a better motor. as far as the LS series goes? if ford built essentially the SAME motor for 45 years it'd be damn good too
how bout some OHC, and dare i say DOHC?
but in reality an LSx is a better motor for racing... a 2v LSx "stage 3 head" will flow 340cfm at .690, a mod 4v "stage 3" figure 225 @ .600, and the LS head is a 2 VALVE, non OHC design.
^using numbers easy to dig up, PRCs on the LSx and patriot on the 4v's
