I am going to perform a transplant on my 1992 Chevrolet Camaro RS. The orginal engine is a 305, it has 185,000 miles on it and doesn't smoke or skip a beat, but I got my hands on a 5.3L from a 2003 Chevrolet SIlverado. My question is will the accesories fit from the old 305 to the new 5.3L engine or will I have to find all new accessories? Also if anyone out there has done this transplant already could you let me know of any obsticles I might run into? This is going to be a winter project. Thank you.

 

do your research many people on hear have done it me included. No the old accesories wont fit the lsx, keep in mind the truck accesories are differant and some holes on the 5.3 are not drilled or taped

 

You cannot run the old 3rd gen accessories on the truck engine, best thing is to get the f-body accessories and use them.

 

yup.

also, you'll have to drill/tap one, possibly 2 holes.

not hard, just do it before you install the engine.

 

Thanks for all the input, I am going to attempt to gather all the needed parts before I start.

 

ok so the thirgen accessories wont work on the 5.3 truck engine but will they work on an lsx bowtie block with l92 heads? i have the 89 serpentine belt setup and dont want to have to get new bolts and brackets acccessories etc..

 

The LSX block is identical to all of the LSx based motor as is the L92 heads. You will have to run LS1 accessories on it.
