I can see a lot of these trucks getting upgraded engines and transmissions. My truck is a original 307, M3 that was converted to a T400. It was good at the time, just not now.

I found a 4.8, 4l60e with 130K on it for $900! add a 1991 blazer tank between the rear rails and for less than $1500 could upgrade the whole powerplant!!

You could also do a ZZ4 short block and newer heads to outperform the original 350 in these trucks.
