    I guess these old 350s are just garbage and don't work in their intended environment or work efficiently LMAO!!

    My brother and I drove from Fort Worth to San Antonio, TX today to pickup a Jeep Cherokee and a stranded cousin. He blew a radiator hose and the headgasket or cracked the head. I had to stop for fuel in Austin which is about 80 miles north of where I was headed. Cruised those 80 miles at about the 80-85 mph speed limit. Went and picked up a U-haul and the Jeep near downtown San Antonio. Then we all drove back home. ~ 270miles loaded with the A/C blasting and running 65-70 mph in 3rd gear turning 2,600-3,000 rpm. Drove 372 miles on 25.8 gallons, 270 of those miles pulling 6,500+ lbs and a trailer whose surge brakes did not seem to like to fully release for a couple of miles after bumping them. Picture was take right befor I let alot of air out of the Jeeps tires and strapped the suspension down with 15K ratcheting tie down straps. The 350 actually pulls the flats in 4th gear but pulling that kind of weight with a 3.73 gear it is a bit lugged for the cam in it. If I had 4.10s and or a 383 or both I would tow all over in overdrive. I did not nail it from a dead stop with the load, but I did kick it down to first gear a few times accelerating from the frontage road onto the on-ramp to better meet the 80 mph traffic. Pulls like a damn freight train from 2,500-5,200 rpm Tow/Haul shift points.
