For a 3100, the engine mount instructions from CPP measures from a specific rivet near the front of the frame to establish where the mounts are to be located.
The 2 ton will not be the same length, so if you can wait until I get my 3100 frame back from the powdercoater, I can measure from the front cab mount holes to where the engine mounts belong.
That should guarantee that the engine will fit ahead of the cab.

Yes, that would be helpful.

For mocking up engine swaps, I usually use a bare engine block and an empty transmission case for establishing the location of motor mounts, crossmembers, etc. Even with a set of heads attached with a couple of bolts to check firewall clearance, etc., it's a lot easier to maneuver than a complete assembly.

The biggest obstacle with a small block in an AD is the distributor. I have enough room to fit my open hand between the big HEI distributor and the firewall with the CPP mount kit.

I don't you think a small displacement v8 will be all that and a bag of chips on a 2 ton truck, Can't seem it being worthwhile for all the work compared to what the 261 can do. So, I think a stroker 383 would be a better power plant unless you plan on driving the truck empty only. Piston crank kits are cheap and will turn a 350 small block into a torquey powerplant with the right camshaft. IMHO

Just stuff a tall block 366 in there and you'll have a real truck engine. 350's are like belly buttons- - - -everybody's got one, and most of them are pretty boring to look at!

Your right , 350 small block is just like any other small block to look at. My point is if he is resigned to put a small block in his 2 ton, get as many cubes as he can so it won't be lethargic.

My son bought a 1959 Chevy 2 ton C 60 this summer. It has a
283 and a 5 speed transmission.

I went on the GM Heritage Center and found that the frame
width on the front of the frame for a 1959 3100 - 6600 to be 34"

The same dimension for the 1951 3100 - 6500 is 35"

It is raining now and will not have a chance to measure but
I will find out the distance between the 59 steering gear box/column
clearance tomorrow. Though there appears to be a lot of room
on the 59 2 ton. Jeffrey

Thanks Jeffrey, that will be useful.
Jerry, that's what I'm trying to avoid. I want this to be an engine update, not re engineer the whole truck by trial and error.. When I was asked about putting an LS1 into the 51 COE project I had a bare frame and bought the foam mockups, block, heads and auto trans to prove it couldn't be done w/o making a new frame.
People have done this, or at least attempted it, before. The beauty of forums like this is that people with experience and knowledge are willing to share it so other people they don't have to reinvent the wheel over and over again.
As far as power goes, the client isn't going to be happy until we have 327 with 300 - 325 HP, so I'm resigned to that. At least it will bolt up to the 700R4.

OK, I'm a little cranky this morning, sorry.
If the rear distributor is a problem, I can have the engine built with the front distributor option.
Does this solve any other problems? Can locating the block without concern for the distributor make any improvement on other clearances?
Because of the 700R4, the rear engine cross member and mounts will not used. Tripod mount - 2 front mounts and transmission tail mount. The rear cross member I made for the transmission is bolted to the frame so it can move forward or rear easily. I wouldn't have had to modify the firewall/floor to fit the transmission in if I could have moved the original engine a little forward.
The small block is shorter than the original engine so there should be lots of room to move the engine forward to clear the distributor unless the pan hits the front cross member. (modify the oil pan)
As I recall the cooling fan on the 283has a long spacer between it and the pulley to get it closer to the radiator, that can go if necessary.
