Quick question i have a 92 caprice 305, i have a chance to purchase a 350 TBI ECM. MY question is, is it as simple as just plug and play? or will any other changes need to be made? Thanks in advance!

Why would you want the 350 ECM, unless you were going to run a 350 in it?

If you go and put that on while leaving the 305 in there, you're going to whack it all up.
