o aaron mr know it all ??? the guy spun a bearing in his 400 supercharged motor that ran 11.5 then he saw my ad for my motor and came to buy and i took him for a ride. then he told me he going with a sbc 454.... theres no replacement for displacment so to say no more power out of a 383 to a 454 is dumb. its a aftermarket block and all. wait... ill just post his pictures up for ya and his myspace link.

go to prostreetjeep.com or whatever.

here we have a simple printscreenrequest button to prove it



moving along heres the old motor in question



ahhh here we have the vechile we spoketh of hah



his new motor sittin in jeep



so if he once told you that he gonna do that ... well he didnt. so dont argue my facts with what you were once told lol.

his new motor makes 600 horse on motorand is ready for nitrous or forced induction... who cares about RPM, with power like that just gear the bitch right and your out.
