Engine guru's, need help, what do I have?

[buckroseau]

Hi,

New guy here. Picked up, what I was told is a 1962. Bit of a barn find. It's been sitting since 1981. Currently is running, not well, but running.

It has an exhaust manifold leak, so I would like to replace that and get a new exhaust welded up before I really start tinkering with the dizzy and points.

I think it is a 3/4 ton, has the 8 bolt hubs. Just wondering what engine I have. Not sure how many options these came with, but I thought I read some where it was at least 2.

Any help would be greatly appreciated. Attached a couple pics from Sunday when I trailered it home.

Thanks in advance, Matt
