Steve Long cams are spot on every time.
Finish is smooth and free of chatter. (has to do with quality of machine and user).
Worth the extra money not to have to waste a bunch of time checking the cam for accuracy.
Engle, and others almost never match the cam card. |

My WEB 110 info is showing IO 23, IC 53. (This is for a 105 lobe center cam.)
108 Lobe centers would calculate to IO 20, IC 56.
Very similar numbers to a E120 at IO 22, IC 51. 108LC although this is advanced about 4 degrees. Add 7degrees for the EO & EC numbers. |

| I’ve a C55 that has about 10 degrees more duration on the #1/#3 intake lobe then the #2/#4 . The exhaust dialed up ok . I liked it and may one day take it to a local grinder and get them to regrind the bigger lobe . |
