LS 5.3 engine 4L60 trans education please

[Red71gmc]

I am wanting to buy another 67-72 and start a build this winter. I pretty much have the general idea of what I want to do other than engine and trans.

This truck will be a driver but I want to go completely through it. All mechanicals, body, wiring and all. Being a driver, I'm not opposed to add the newer improvements if they are improvements.

This truck will haul normal 1/2 ton truck loads now and again, and will tow a normal 1/2 ton truck trailer now and again (4-5k). This truck would see some miles doing this if I do the build correctly.

I have rebuilt one 350 about 25 years ago. I think with a good book or forum as this I can handle it again. However, the rebuild 25 years ago was all stock and I have no background in mods unfortunately. I am not a beginner nor by any means an expert. Everything I have done pretty much was for utilitarian reasons for business needs to accomplish a needed task or save money to complete a needed task for business reasons. Now I want to play a little.

I originally thought I would go a mild upgraded 350 built by me or a moderate 383 built by someone else with the knowledge of them and how to. The more I read about the LS swaps I'm thinking maybe this would be the way to go in a not so original driver build. Modern engines are nice for a hard driven driver and it seems some of these 5.3's with some mods are doing wonders.

I have been reading up on the 5.3 and have myself more lost then when I started the research. It seems there are a bundle of variations, generations and that's before you get into the transmissions to go with.

I'm looking for some real experienced folks to head me in the right direction for my needs. All the while keeping in mind I'm not a mod builder. I don't ask for much lol. Thank you
