I used to use the Crane 278 HMV as the go to cam in 10-1 400 engines. 222/234@ .050. .467”/.494” lift, 114 LSA. The catalog said lopey idle but that wasn’t the case. Don’t pay attention to cam company literature.
Smooth idle in gear with a stock torque converter, drives like stock and would run up to 5500. Easy mid to low 13 second cam in stock late 60’s 400’s thru manifolds on street radials. I think one of the Summit cams is pretty close to those specs and should run virtually the same.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
