I don't think I'd do it in a half ton - the weight is about double for any other engine you might have had.

You might consider finding an F250 or F350. The suspension and frame in an F-100 is a little light for the roughly 1000lb 6BT.

It is very common for people to put the Cummins 4BT in 1/2T pickups though...

F1 is a 48 - 52 1/2 ton.

Should be just as easy to find a 3/4 ton + as a 1/2 ton.

They aren't as easy to find, but they are a good engine and about 300 lbs less then the 6bt. The 6at was originally used on onan gensets, but an automotive version was brought out in the late 80's. Lots of UPS trucks were repowered with them. I'm running one in my 3/4 ton gmc, and I bought another off cl that I hope to put in my f350 fridge. Almost same dimensions as the 223 six that's in there. 220 cu in and 120 hp, but I've read that they can be made to produce a lot more if they are tweaked. I've seen some youtube videos of them in various trucks, even jeeps and landcruisers. Very simple swap really and there's no doubt it's a cummins under the hood.

Almost correct.... for '52 it is...

but in 1948-50 and perhaps even 51

F1 was the 1/2 ton: gvwr 4700
F2 was Light Duty 3/4 ton: gvwr 5700
F3 was a Heavy Duty 3/4 ton: gvwr 6800
F4 was a 1 ton: gvwr 10,000 for one variant
F5 was 1 1/2 ton
F6 was 2 ton
F7 was 2 1/2 ton
F8 was 3 ton

From F4 on there were multiple gvwr's depending on tire size and if dual rear wheels.
The ratings don't really mean much in the real world AND they were different for Canada
