360 motorhome motor

I would search the cam companies listing for the recommended largest cam to use with the stock high stall converter and then add the Rhoads lifters, headers I to a 2-1/2 exhaust, dual plane intake, 600 to 650 carb and a upgraded ignition like a MSD. IF you can spend a little extra coin on roller rockers, go for it.

I would not use a Performer intake but the rest should be excellent for the application. Action Plus, RPM or the LD340 would be great. They can be found used for good prices.

The other parts I would purchase new.

You can make a honest 350 HP.
