1961 d500 flathead and 4 speed

[712edf]

If flathead then could be 230, 251 or (according to Allpar) 265.

I admit I know very little about the Mopar flatheads.

It's not a slant 6. It's a flathead, I wondered what displacement it would be.

I think the 6 cylinders were the new slant 225. V8 could be (poly) A318 ,maybe a 361 but I'm not sure if they were offered that early in trucks. I know passenger cars had their 361 by then.

Transmission would be a New Process 420
