Hello. I found this site a couple weeks ago, and have spent many hours already reading up on the proper ways to put a Gen III motor in a '91 Chevy ecsb. I thank you all for the info I've found already as well as for the info I'm sure I'll get in the future. I'm in the process of gathering parts to swap an '05 L33 5.3L into my tired old pickup. I've got the engine, factory harness, and ECM. This engine is very new to me. I've always took the easy way to go faster and just put a big block in all my past projects. Now I guess it's time to learn some new tricks.
