Ls1 stuff doesnt really cost that much guys. They also come with GREAT heads from the factory, I dare say you could get to the 500whp mark in an LS1 cheaper than you could in a 4.6L 99-04 (year/year comparison to LS1)

 

Thats it to beat a ls1, is a cat back and headers and cai...

 

did you just throw that out there for fun? or was someone actually saying otherwise??

 

How do you figure that? LS1 weighs the same, has equal gearing, has a better power curve....please explain.

 

I agree, it takes much more than that for an lt1 to run with an ls1. Usually full bolt ons and a slightly hotter cam should run with a stock ls1.

 

I threw that out there for the people saying stuff was cheaper for mustangs...maybe by a little, but the power returns are way less.

 

yep, they need a cam so they dont fall off in the low 5K rpm range.

 

lol....

 

All else being equal it's approximately a .8 difference, so whatever it takes to shave off .8.

 

Maybe if you're talking about 302 pushrod parts....but not OHC stuff. Hell, the LS1 aftermarket as almost become as large as any aftermarket for any car to date. It is the new SBC for all the old hotrodders.
