5.7 liter Caddy engine swap or 5.3 Chevy engine?

[gmc684x4]

Gen 2 Ltd distributors suck
Hit a puddle hard they fail
Plan on replacing it atleast every 2 years
It will be obd1.5 which is obd1 wiring with obd2 port scan tools usually won't read it with out rewiring it

I had a 94 z28 loved it until I learned the issues with the poor dizzy design

For anything more then free I would give it a hard pass
Look for its son gen 1 vortec l31 or better yet find a 4.8 5 3 or 6 liter

I got a good l31 free in a van and a good 5.3 in a truck there out there
