Help with 360 swap?

Then you'll need adapting motor mounts or K frame swap. Consider exhaust and radiator. That slant had a 904 behind it, so if you go with a 727, you'll need a shorter drive shaft.
This motor mounts are hard to come by I’ve got my feelers out there. Was planning on a new full dual exhaust and a new radiator the one in there now is tiny and seen better days. So the trans pan that’s on there now being out of a motor home you think will fit
