Seems to be in good shape. But before I ask the seller for more info and pictures, how well would this truck do loaded down with tools 'n stuff?

I want to setup a service truck so I can do road calls for tractors... something that I get asked often enough every year, but have to turn down since I don't have a truck equipped for it.

My '61 5000 has the 351 and that seems to do pretty good loaded with tractors, but I never had a chance to drive a pickup with the 305. After I load the boxes with tools, parts and mount a compressor and my Lincoln welder in the back, do you think the 305 will handle it okay?

Not looking to fly down the highway, but it would be nice to pull the secondary roads without having to downshift on the hills around here.

Greetings Tractorguy!

Your 305 will be able to handle it just fine. In my case, we had built high box sides for the purpose of hauling grain. You will note that my truck was a 1963 Chevy 30 (1 Ton Stepside 9' box) that I re-powered with a 1962 GMC 305 V-6. This is one that I wrote down in my notes, as it is a testimonial to the ability of these engines to be absolute work horses. I hauled a load of Winter Wheat to our local grain elevator, and my truck weighed in (without me in the cab) at 13,500 pounds loaded. After unloading the grain, my truck (again without me in the cab) weighed in at 5,250 pounds Empty Weight, which means that I hauled a payload of 8,250 pounds (4 1/8 tons) of Grain in my truck. I didn't even need to use granny low to start the load moving. That old 305 had absolutely no problem whatsoever hauling that load to the elevator, so your 305 should be more than up to the task that you are asking of it.
