I guess everyone is kind of confirming my suspicions that it would cost less to just get a 'new' [to me] engine. This is for my other car with a 4L60E in it. When I drop the engine back in I'd like to be able to just fire the car back up and get it out of there instead of having to wait for a chip burner to write me a program with it. If I use an engine with a carb on it getting everything to work might be confusing and take me days... If I use a newer LS getting the computer to work might be a real headache without switching to a different trans, and I really don't have money to replace the trans too.. That just leaves the LT1 at a cost of about $750 - $800 but I was trying to avoid that engine so I didn't have to redo all the computer and wiring... hence the 'rebuild this engine' w/ the crappy offer
Also, I suspected that putting the LT1 behind a high mileage trans might cause it to fail with the sudden introduction of 100 more hp behind it?
