been debting wether or not to swap out my engine i have to 4.8 right now and i wanted to swap out to a 5.3 im pretty sure everything from mine will bolt on to the 5.3, but as far as the wireing harness would i need to get that with the engine i drive a 2006 silverado 4x4 cc and does it have to be a engine out of a 4x4 and also whats the best 5.3 lq4 etc and how can i tell them apart
4x4 or not doesnt matter just use the your motor mounts, also are you sure you dont have a 5.3??? i thought all z71 were 5.3s 5.3, 4.8 is stamped on the block behind the front accesories, an lq4 or lq9 there will be a 6.0 stamp on the block, one easy way to tell which one you have is what vehicle it came out of, also if you do have a 4.8 swapping to a 5.3 really isnt worth that hassle.
ya its a 4.8 they guy i bought it from put the z71 sticker on there and changed the suspension ya i know its really not worth it but this summer gas is gunna be to much to have a 6.0
well it should be an easy swap everything is pretty much the same.
thats why im gunna do it so should i get a engine out of a tahoe or something that has more power than just a plain old 5.3 and does it matter if its an lt or ls
They are ALL the same....Unless you find an L33 but chances are ull just get an iron block
what kinda of truck is the l33 im kinda new with all these different engines
THE L33 is a HIGH OUTPUT 5.3 jut google what they came in, an l33 is an aluminum block 5.3
Alum block and flat top pistons.
i though the 5.3 came with deep dish pistons or is that just on the iron block
