As you probally already know stroker motors eat up cam duration
So don't be shy on pcking a big one
Keep in mind the converter and camshaft need to work together to make the most, best use of both
I'm thinking between 250 and 260 duration at .050 on both lobes, ground on a 106 to 109 lobe seperation angle and installed 4 to 6 degrees advanced on the intake lobe
with as much lift as you can get, maybe even use 1.6 or 1.7 rocker arm ratios if you can
The pushrod clearances to the block and heads can be a problem on the higher rate rocker ratios on BB Mopars
Measure twice, grind less
