    Hi, my friend has a 1994 1500 silverado with a 350 tbi that is on its last legs. We have located a 1990 silverado with a poor body, but a strong motor. We are considering swapping his engine for the 1990s, but first would like to get some tips from people who have in the past attempted a similar project. If anyone can pass on some tips or pictures from a past 350 tbi swap it would be greatly appreciated.

    Its actually a direct bolt on process... You will want to swap over the TB off of the bad engine to the new engine and a few of the sensors you will want to swap so the plugs work properly.
    While you have it out i would take the time to Put in a new oil pump (just a precaution and so you dont have to mess with it incase there is a problem once it is in the truck), and clean the motor up, Also if there is a few extra $ around i would buy a set of shorty headers for a 1994 Chevy from Summit. that will eliminate those stupid exhaust doughnuts.
    Also replace the rear-main seal since these motors are notorious for leaking from them.
