1970 360?

Well I bought this motor last night. It came out of a 71 motorhome.
The casting number on the block is 3418496.5.360.

I couldn't make out the numbers on the heads, but there is a big J embossed in the heads by the exaust ports.

It also has a 727 that came with it. I got it all for $250.

Its fairly clean, I pulled the valve covers last night and there is some surface rust inside on the top of the heads and the push rods.
So guess I'll pull it apart and give it a overhaul.
