Rule states.....Solid Cam with maximum .470" valve lift. Cast head with no port work allowed and head is 55cc with 10:1 compression engine. I run ford 2300 on a fast low banked 3/8 mile asphalt track turning max around 7500 rpm. Looking for competitive cam or at least maybe some good specs I should be looking for on a cam to fit my needs. Thanks in advance!
