Thanks for the input guys. I appreciate it. However, my project is about to take a pretty sharp turn. I have almost everything I need for a TBI install, but came across a whole lt1 setup, engine/4l60e, with harness and pcm for about $400. It has about 150k on it. Supposedly it was running good when pulled so I'm hoping for the best. Is there maybe any quirks I should lookout for engine/pcm wise with this install? Should I make a new thread for these questions? I'm sure I'll have many more that come up.
This should all be going into my 70 chevelle that's been sitting in a barn for more than 20 years now.
