New to the forums. Currently have a 1993 4.3 tbi with a 4l60e. Just had the 4l60e rebuilt, did my research online and found they were year specific 93-94 being the only two years I could use. Now that I have the transmission rebuilt it's time for a 5.7 tbi swap. I've done my research and answered most my questions. But this one, will any year (88-95) 5.7L tbi work with my newly rebuilt transmission? as long as I keep the original 93 computer and rechip it ? Or do I need to find a 93-94 model 5.7 to keep the swap as simple as possible?

Any should work, I did this to a 92 4x4 but instead of TBI, I swapped a TPI into it with a harness from street and performance that worked with the existing wiring. Extremely easy swap.
