i got a 1995 dodge ram 1500, love the thing. oil pressure jumps up and down so i use lucas oil stabilizer, and pressure hasnt been jumpin around as much. Someone said use restore engine treatment and it worked better. anyway, if my motor blows, i was thinking about putting a 360 in it. is it a direct swap? do i have to swap anything else?

 

There are a ton of 318 to 360 swap threads already in here. A search should answer your questions.

 

What is the range that the PSI jumps around?

 

the psi starts a little over 40. as it warms up. without the lucas, it will go so low that the oil light will go on. i put the lucas in and never had that trouble.
