1974 power wagon questions

I have a '74 power wagon with a 318 94, 000 miles. I have purchased a edelbrock performer intake, a holley 600cfm carb( both are installed, intake ports ground to fit gaskets, heads have not been touched... gas dam going into heads remains for now), headers, x pipe, resonators ( not yet installed).

I also just accuired a '75 Minnie winnie Winnebago with a 360. I don't know anything about the rv, not sure if it runs. I just want my wagon to have more power.

I thought the 360 RV cam would help in my 318 but do I use the valve train and rods from the 360 or can I just use my original 318 stuff with the new cam? Is this a "take one part out and put a new one in" thing or is there all sorts of specs and math to be done?

Thanks in advance!!
