Comp XE268H v Crow 18619 - 318

Because you’re talking about a stock stroke 318, I would go with this one if it were available.
Hydraulic Roller Rattler Camshaft; 1964 - 2003 Chrysler 273, 340, 360 1800 to 5500 Howards Cams 718005-09 | Howards Cams
But if you can’t find one, Oregon hydraulic roller grind 1386. 224/[email protected], 280 advertised, .525 with 1.5 rockers. It comes on a 110 LSA, but get it ground on a 108. FWIW, in your combination and goal set, I would go with the Oregon cam on a 108 with a set of 3.23 gears and a 25-27 inch tire, and I wouldn't look back. Most 2500 rpm shelf converters are going to be on the tight side. There are a lot less complaints about selecting a cam that may be too small for the combination as opposed to one that is too large.
