first post, not sure if in right section, please inform me if it isn't. I have a 5.3 and 4l60e that I'm going to rebuild for my truck, I'm looking for a list of all interchangeable stock parts, (pros/cons, best combo, etc.). I work for a dealership and have access to a lot of parts, not trying to go crazy, just a fun and different build for a daily driver. I know performance gains will be greater with custom aftermarket parts, but I want it all stock GM parts for the ease of access. I also think it would be cool to build a Frankenstein motor using all stock parts, seems fun. Thanks in advance.

There are going to be parts from GM that are more expensive now than their aftermarket alternatives.

Jsrobbs,


If you're looking to stay factory GM everything on your build. You could run a factory c5 2002-2004 Z06 cam 204/218 duration - .550/.550 lift - 117.5 LSA. Find a set of 243s or 799s and mill them a bit to bump compression. I had my stock trans converter reworked on my 2010 which helped as well. Grab some rear gears out of a GT4 G80 truck if you're looking for 3.73s and LSD.


If you want a set of headers cheap, Pacesetter has some decent stuff for cheap. I had a set of their LTs and O/R Y-pipe on my 16 5.3. No issues.


Good luck with your build and if you have any questions at all, fire away! Welcome to the site!
