Mopar 318 5.2l rebuild/upgrade

Hang on man, you're off the rails already.
What's that camper weigh?
What transmission ?
and what gears?
and what year Magnum?
And why did you not start with a 360?

I am willing to learn educate me

- 6400lbs/7700lbs
- 3spd with overdrive with granny 1st and 2nd A500 or 46RE (none of the shops able to tell)
-3.92 rear end with 16R75 (actually I have 80 on the back)
Vehicle year is 2000, 5.2L, 318CID, SMPI V8, with 225hp 295 ft.lbs what the boos says.

I know 360, it may comes into play if parts I have are junk and I need to replace them. I want to spend reasonably. Economy and torque I need.

I am even thinking tranny swap to manual just read Dakota's or 80s rwd Supra would fit, maybe I could live with the hp/torque i have as stock then.
