O.K. here is the deal , i have a chance to buy a 5.3 barely used eng. from a 1/2 ton p/u , 02 i think . price IS RIGHT , it's a long block , iron block , alum. heads . it has no acc. , no intake , no exhaust man. , no coil packs . did i mention the price is right ? my thoughts are to p/u a clean v-6 and do a transplant with a t-56 . i know about suspension etc. , yes eng. will be freshened up . yes i also know this will not be a weekend project . my problem is i know NOTHING about these engines . can anyone reccomend a good website that i can do some research on these engines , or better yet what series this eng. would be ? thanks , you guys have never let me down before . remember the only dumb/stupid question is the one that is not asked . yes i did a search . thanks .

 

if its a 02 5.3 then i believe that would be an LQ3

from what my brother knows(has one in his wifes 2000 something reiner)
he says its basicly an lsx with different heads

 

The price isn't good when it's a longblock and you need to find and put everything back onto the engine. It'll be cheaper to just find a complete engine.

This isn't a third gen engine. It's an LSx engine.

 

Yes, it is an LSx engine.

So, let's move this to that subforum.

 

thanks guys , i knew someone would steer me in the right direction . thanks again .

 

And read the sticky https://www.thirdgen.org/forums/ltx-...want-swap.html , of course.

You might be able to piece things together. I've seen PCM/harness for sale on eBay. Haven't seen coils, though. I'll have an LS1 intake available soon.

What are you going to do for a transmission? Earlier transmissions are not a direct bolt-on.

 

T-56 would be my choice , anyway as i mentioned in my first post this is an idea . the engine is free/almost so i'm going to give it some thought . thanks .

 

ls1tech.com will be where to start. Free is a good price indeed you cant go wrong with that
