360 vs 440 79 coachman

I was looking at magnums and they go for like 1500, no trans, since the 440 powered rv with the Swiss cheese frame is right besides the one that has the 360 iits the logical swap for me atm
Oh, well if you’ve got a 440 donor RV on hand already, then absolutely I would do the 440 swap over a 5.9 magnum swap.
