Bore x bore x .7854 x stroke x # of cylinders.

Example: 4" bore, 4" stroke, 6 cylinders
4 x 4= 16
16 x .7854= 12.5664
12.5664 x 4 (stroke)= 50.2656
50.2656 x 6 (# of cylinders) = 301.5936

I run the 3.75x3.75 in my 66. It is a super 55 engine with the late 550 head, manifolds and carb. The head is shaved .100 and everything else is stock. It pulls really well most of the time. You can see it pulling on youtube. 2014 Pa Farm Show Antique tractor pull - YouTube. It won the 3,000 and got 2nd in the 4,000. Lots of fun!! I use Sunoco 89 pump gas. I don't have the PTO in it so I don't know what the HP is, guessing more than 50 @ 2600RPM. Your 77 should be 60 or better at a lower speed with 3.875.

60 without doing head work or after?

With the big pistons the head work will make it much better. Or get a late 770 or 1550 head for it. I'll try to take a look in my Oliver manual to find the valve sizes. The later manifolds and carb might be a good thing for that engine also. The later upper end really awakened my 4 cylinder. I worked on the carb this year to get rid of a lean problem on a long hard low RPM pull. I like it now, good torque at lower RPM.
