I think something in the 250° duration would work well, but you might want some steeper gears.
FWIW, I use a XR286R solid roller from Compcams, 248/254 duration with .576/.582 lift
.and I think my cam is WAY too small. Someday soon Im going to switch to something in the 260+ duration with .600+ lift..........but, I do expect my current combo to run in the high 10.60's to low 10.70's this fall after all the carb tuning I've been doing lately.:toothy7:
