[POWERSTROKE]

The truck would be a " Must Buy" if it had a 351 V-6, even a 305. But with an in-line 6, better make sure it's not the 230 cid. The 292 would be preferred but 250 cid is more likely installed. I drove a lot of in-line 6 GM trucks driving pkg car for UPS. Our terminal Up-sized engines in everything they could. 230's replaced with 250's, and 250's replaced with 292's. Then one day I had a pkg car with a script FORD on the horn button. That truck ran up the hills on my delivery route like a well tuned V-8! The night shop mechanic said it was a 300-6. Year or so later I bought my '78 used F-150 4wd w/300-6 & 4-spd. And to think I almost ordered out a brand new '78 1/2 ton GMC w/292-4spd.
