Stock bottom end 360 magnum
I just used headers (Hooker Super Comps @ 1-3/4), JY distributor & Chrome box, B&M flex plate, RPM intyake and 600 carb. Slide in a cam and callit done. Never to the track, but a nice easy going but yet surprisingly powerful ride are the descriptive words given to this when I have first timers in the car. They all love it. Backed by a 727/2800 stall & 3.55's on 26-1/2 tires.
This is a '79 Magnum FWIW weighing in at just shy of 3700lbs. empty.
I'm trying out a little diet for it.
Good mention
@tonysrt an oil pump is cheap and a good thing to check.
