Waiting on my 5.3 w/ 4L60E to be delivered. Pulled my old carb'd 4.3 from my OBS truck ('86 Silverado C10), and am dying to get this project complete. At the moment, I'm considering how I'll be attacking fuel delivery.

Check out www.hotrodlane.cc. They have a writeup on a '77 LS1 swap in their S&P Projects section that's interesting. Some of which can be considered for a LM7 swap. What I'm seeing is that the following things I have to consider:

* Fuel delivery: Elec pumps (2 for saddle tanks), valve switch assembly, and in-cab switch
* A/C mods: hoses and connections to compressor
* Power Steering: slight line mods from steering box to pump assembly
* Radiator: look for NBS radiators, plus transcooler
* Gauge cluster: Decided to bite bullet & go with Dakota Digital cluster
* Driveshaft
* Rear gears: upgrading from open-end w/ 2.73s

Good Luck, and please post. This is becoming popular, and I'm sure a lot can be learned.
