In this thread I'm going to compile links to; build threads with Chevy small block swaps, Chevy Lsx swaps, and threads that contain information for Chevy power train swaps. As well as the links to commonly used parts retailers.
These list are nowhere near complete, if you know of a thread, or useful part I've missed post it, use the same format if you can to keep things easy for people to search through.

Gm Conversion Radiators
In order from cheapest to most expensive. Remember, sometimes with a higher price your just buying the name, yet at the same time, you get what you pay for..... I only included a few, these are the main ones I see people using.

Champion Cooling $210
Amazon.com: Champion CoolIng Systems, CC8102, 3 Row All Aluminum Replacement Radiator for Jeep Wrangler YJ *(Chevrolet Conversion): Automotive

Advance Adapters $415-$576

Novak $589
Radiator for the Jeep YJ Wrangler with Chevy & GM Engines

The cheapest, and possibly best, route would be to use a universal GM radiator from one of the big three (Summit, Jegs, Speedway) BUT, they will not simply bolt in as these do, you would have to figure out a way to build mounts for it.

Another option would be to find a local radiator shop. Talk to them, tell them what your doing and see if they can custom make you something. Support the local man, it pays off in the long run.

LSx Wiring
There are several options when it comes to wiring a Ls motor. If you feel like putting in the time and looking to save a few bucks cutting down a factory Gm harness can be done. Many companies such as Painless make pre-made wiring harness'. Then there are new, custom harness that can be bought to fit your needs.

Tbi Performance
In this thread the guy is building a 350 Tbi, uses vortec heads and an LT1 cam. The motor was built with low end power in mind. All the posts are educated and seem like good solid information and advice. Covers various situations that arise while trying to modify a Tbi motor.
