The rusty ram

I've been doing alot of thinking and considering about the future plans for this truck. I haven't finished the body work or the bed yet. I still need to replace the rear leaf springs. And find out why I keep blowing reverse fuses. But I know I have to replace the clutch in the near future especially if I plan to daily it and use it to tow the dart. Considering I don't have a garage or a concrete driveway to drop the trans from the bottom and roll it around do you guys think it would be easier to just pull the engine and replace the clutch out of the truck? And while it out I could freshen the engine or even replace it with a 5.9 mag I have. I've had alot of different thought about it. If I did the 5.9 the ecu/pcm would have to be tuned or flashed which i don't have a tuner to do that with. So that's more expense. Idk what im gonna do yet.
