340 Six Pack Engine Specs

Unless You're going for a 1000 point resto, I wouldn't be too hung up on that particular cam, especially from a grind standpoint. A smaller overall duration modern grind
will idle better and perform as well or better than that piece. The bottom end with that cam probably lost a little when put in an auto unless You put a little looser torque
converter in, is Your ride a stick, or....?
