ladies (if any) and gentle man, i got my self a 2001 silverado with the 5.3 that i wanna lay some rubber with. i got it stock and raced a 2003 dodge hemi 5.7 and i lost. since then ive installed a k and n fipk intake, edelbrock shorty headers, flowmaster muffler with 3" pipes from the y dumped. i also have the hypertech power programmer 3. well thats all it took for the hemi but i got lightning in crosshairs. i want some nasty heads, cam, intake manifold, a real exhaust system nelson tuning suspension upgrades. i also need help with the tranny and rear end. i have the stock 3.73 posi now. im hoping for an sts turbo in the near future. but heres is the problem. i have no idea which parts i can swap with or performance parts that i can upgrade to.

so heres my question. i hope someone would be cool enough (who has worked on a 5.3) would provide a list of what parts (manufacture and part #) everyone has installed that would be great. if you can keep in mind i live in california where the smog laws SUCK

and thanks again. i love this site. you cant buy knowledge like this.

ive been reading the differences between the 5.3 and the ls1 and im not sure what the difference is. different people have different answers. i saw the cam and it says for engines 350-383. does my 5.3 take parts that fit a 350/5.7

oh and by the way great suggestions and i do appreciate the help.

ya that would work for your truck

the old 350 small blocks... such as a 327, 350, 383... im pretty certain that there parts wont fit the LS motors. here is a good article explaining all the LS motors ex. 4.8, 5.3, 5.7 346 (LS1) (not a old small block chevy 5.7 which is a 350), 6.0 etc.

what years of gm can i swap out. like ex: the heads of a 86 corvette fitting the 5.3 on a 2001 silvy

check the Lingenfelter 2-3 camshaft, AND a Magna Radix supercharger. The Lightning will be in ur rearview with the 3.73's. btw, welcome to the site

even if you could which im 99% sure you cant you wouldnt want to. keep your heads, just get them flowed and everything else i said... your heads flowed are better than LS1 heads flowed cause the compression will be higher
