Oh, I was talking about if you’d be using a 5.9 magnum. If you swap in a 440 and the matching transmission, it may or may not change the driveshaft length, I really don’t know either way.
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
