Is it a 383 or a 361?

Looking at a big block in the local U-Pull-it. It is in a '68 Dodge pickup. It appears to be of 1968 vintage. It is a 3/4 ton pickup. Now, would this be a 383 or a 361. I didnt have time to scratch away the crud on the block. Just thought Id ask cause I was assuming that it was a 383 then someone reminded me that they continued to use the 361 in trucks until the end. It is 2- barrel. all there with the 727. Anything stand out on the truck 361's for identification?
