Mopar 408 cam ??

Hi mate, glad to hear the 360 build is going strong. I've done something similar but without stroking her to 408, just a .030" overbore with Keith Black hypereutectic flat-top pistons and a Scat cast crank, topped with ported and decked 318 heads that have 2.02" and 1.64" valves fitted. Compression with the 60cc chambers is about 11:1 or so.

I'm using a Crower 31243 grind which is INT/EXH .480/.503 lift and 227/[email protected]" duration. Slow ramp rates by modern standards and rated at 1800~6000rpm by the manufacturer with emphasis in the comments on "9.5:1 compression or more", "headers and 4bbl carburettor", "helped by mild port and larger valves".

Anyway... aside from an outdated Crower 31243 grind... I would recommend the Comp Cams XE275HL - the 'L' is for extra Lift which is provided by faster ramp rates. They are developed for larger diameter Chrysler lifters (.904") and work a treat in modified LA smallblocks. Many magazines have installed this specific camshaft in smaller capacity combinations such as modified 318ci blocks and found them to be excellent performers.

I would definitely look into the XE275HL for a 360+ build as it will let it breath nicely and should be easy to drive with the profile mellowed by your intended 408 cubic inches!
