Last year my son bought a 97 S-10 with the rompin stompin 2.2 engine and a 5 speed. A couple weeks ago, the engine started making some VERY bad sounds, it locked up tight on the drive home.

Over the weekend, I found what is quite possibly the most rusted out 99 S10, also a 2.2 but with an automatic. It runs and drives well, just suffering from a terminal case of tin worm infection.

The plan was to swap engines and scrap what was left. Pretty straightforward, until I had the trucks parked side by side. The 99 engine looks very different than the 97. My local salvage yard shows the engines technically don’t interchange, but isn’t sure what the difference is. Swapping intakes or exhaust is no big deal, but before taking either truck apart I’d like to know what I’m getting into.

I paid 400 bucks for the 99, I figured the 4.10 limited slip rearend and wheels/tires are almost worth that.

Anyone in readerland familiar with these engines? Thanks.
