Low compression "build" and cruise rpm?

73 duster. I bought a 78 440, probably from a motorhome, that looks to be in great shape and came with a ch4b intake, no carb or distributor. I'm thinking about a whiplash cam, Schumacher headers because I hear they fit great, no idea on needed carb preferably a cheaper option. Converter stall?

I would like to be able to run 75mph with the most gear I can. What's the max cruise rpm without tearing up the motor? Would love a 200r4, but probably will end up with the727.

And yes I would love to build a stroker with a turbo, drag radials, meth injection, and be the next john force but let's face it, if it sounds cool, looks cool, can lay a couple patches here and there, and go on road trips I'm set. Not concerned about mpg.

I just made a long post about this.

Cam choice is critical. The cool of a rough idle will wear off quickly when the engine is a pig, burns fuel like a cargo ship and runs hotter than a 20 dollar pistol.

You’ll end up needing a stupid amount of initial timing and to get it you’ll probably need to hook the vacuum advance to manifold vacuum. That’s a shitty way to tune an engine.

You need to be very close to a stock cam. Why make the engine a nightmare to tune, piss away fuel mileage, run hot and not make power where you want it?

Cam according to your compression. Not for sound.
