New Cam Advice

71C10 wanted to see the differences between my old cam and my new one so I found the old cam card.The cam that was in my car when I bought it was a Crane solid roller part # 138021,valve lift was .567 for intake & exhaust,duration @ .050 was 234 intake and 244 exhaust.The new Comp solid roller is part # 11-771-8,valve lift is .646 intake & .653 exhaust, duration @ .050 is 242 intake and 248 exhaust.For what its worth,the old Crane cam lasted for over 15 years,and if I had of known that the squealing noise that I thought was the alternator was actually a lifter,I could have put new lifters in and probably still be running that cam.
