Well, Bob W was right that there was a 305, but I typoed and it was supposed to say 351. This was a TRUCK not a pickup. Had an Army Deuce and a half bed on it. Got 8 whole miles to the gallon. I can tell you stories about running out of gas in Wyoming about 3 miles out of town and what it cost for an interstate service call.
But you couldn't kill that motor with a bazooka. In fact a farmer bought it off of me after I got to Iowa and didn't need it anymore. He's still using it. That thing was a tough old Bastar&.
