Size for the GM 350 and the Mopar 360 are about the same. Weight is about the same. The biggest issue will be the Mopar starter location. GM has the starter on the passenger side, Mopar is on the driver side. Usually, the driver side is pretty congested. If there is room for the starter, and you don't mind the hassle the Drive shaft will present, I'd go for it.

Years ago I put a 318 in a mid 60s Chevy truck because the guy kept blowing up 350s. I told him I had a motor that would outlast the truck if he kept oil in it and didn't overheat it. He pounded on that 318 and did everything he could think of, but the truck gave up before the 318.

The 318 in the mid 70s Pontiac was a bit of a challenge, and the 318 in an 82 Jeep J10 was another challenge. Gene
