Say what you want.. FIND me a gt500 that will run a number without slicks and suspension work...
and I dont know how you do you "stages" but a header, 2.38 pulley and a cold air on a lsa will make WELL into the 620s..the 13 gt500s are very well endowed from ford.. 15#s of boost from the factory. Factory cold air, factory big throttle bodys and a 2.3...
