LS1 Swap Question! Please Share your Knowedge!
as long as you take all of your stuff and put it in the other car I dont think there will be an issue though I seem to remember something about the gauge cluster being unique to the 98 year as well.
Mechanically no problems super easy swap.
Electronically not difficult there are just somethings you need to be aware of, as it will all connect to the same but some minor differences between the 98 cars and 99+ cars exist in the wiring.
I seem to remember a thread popping up similar to this not long ago though where the person just took his engine harness and ecm from a 98 and put it in a newer fbody and had no issues. so hopefully someone will chime in and confirm
