What engine would you build for a Ramcharger?

I had a friend , the late Jim Mitchell) (went by MRMOPAR) he's deceased but we must have built about a half dozen ramchargers
He had a stroke and I got to liquidate his hoard of spare parts
I too like the roller 318 motor
cc and maybe mill the heads try and get a true 9:1
check the seats and especially the middle exhaust guides- if you need guides post back cut for viton seals if not already the two center run hotter
stock valves should work fine but do a better multi angle valve job. back cut the intake if not already- the usual good VJ
me I'd use larger valves with 30 degree seats then a .060 45 and 60 then a 72 and pocket port (given the more low flow with the stock small lift cam
QJ a good idea (I like TQ's myself) Magnum manifolds should work well depending on where your drivers side dumps, if not try Jeep (there are several)
with moly rings I'd do a few strokes with a medium rigid hone and then finish with a fine bottle brush (moly rings) I like ductile tops with any hard working rig

on the 360 you have to figure out how to get the compression up so do the math with the 302 heads you just cc'd 302 heads will be fine and better with a little DIY port work

Magnum tempting get a complete 94-95 EFI from the wrecking yard (no tranny BS) you can run the 318 cam and lifters 0r drill the heads for early manifold
