Will a 77 Charger 360 fit in a 65 Valiant Slant Six Painlessly?

^^^ exhaust is the probably the most expensive and difficult part of the whole gambit.

track down early A V8 pieces, track down 340 pieces and cobble together head pipes, early magnum on the pass side and [question mark] on the driver's side and figure out from there, TTI, dougs, sanderson if you have an automatic; fenderwells if you want to cut. modify the x-member if you want true duals.

might need to beat the seam in the firewall flat to fit the trans.

you'll need to track down a V8 center link.

oil pan from B may or may not work.

early K's are the same 8 or 6 so you could hustle up some stock mounts in lieu of conversion mounts.

figure out trans linkage & kick down, if you have rod style throttle you'll need to scare up a pedal assembly.
