Probally a head gasket on that truck. I havent heard of many of those trucks with cracked heads. Maybe warped, but not many cracked.

I was able to rebuild a whole 6g72. I did all the work myself (aside from the machine work and setting up the crank), and although I am good with technical junk, I wouldnt label myself a mechanic, and certainly not a engine rebuilder.

BUT... it went very well, and with time and patience, it was rather easy.


fyi... they'll crack if you drive the engine without any coolant in it until it won't go anymore. That's how I got the '90 black truck for $300. Amazing thing was that the short block survived! I just put two good heads on it. It cranked right up and ran all the way to NC from GA!!

These trucks are TOUGH!
