As far as a resto cam the only one from MP is the 268/284 w/.454 lift If I remember it all correct. That's the magnum grind for OE resto.
Comp cams sells one with just a bit more spec that works fine in a 440 , they cal it their resto version. Nice cam, just used one in a stock 440 magnum. I'd use it over the MPcams right now.
Ifyou're talking your 361 I'd go smaller. A look thru Comps catalog online would net something nice.
"In 1968, the base engine was a 383, with heads, intake, cam, and exhaust manifolds from the 440 Super Commando; those made it the fastest 383 ever, with 335 (gross) horsepower."

Yeah but that's a base-model Roadrunner. The base 383 in C-bodies was a 2-bbl and made 290 hp. The heads should be the same across the board- 906's in '68. A 4-bbl intake and HP exhaust manifolds would probably wake a 2-bbl 383 up pretty well, even with a smaller cam.

440-4V Commando (Power Pack according to the FSM footnote?!?) Intake valve lift = 0.450" Exhaust valve lift = 0.458" Intake duration = 268 Exhaust duration = 284
There's no mention of a 383-4V, or the 383 "Roadrunner engine", that I'm about 98% sure existed at that point. Why, I'm not sure. I'm also a little unclear on the 383-4V info from a few other sources. They indicate the 4V being 10:1 compression, rather than the 9.2 in the 2V, but I can't tell if there were other changes. HP went from 290 in the 2V to 330 in the 4V, and maybe the compression ratio, HP mani's, and dual exhaust was enough to do that, I'm just not sure.
