The cam that was in the 496 that I sold had a howards cam in it with direct lube lifters. I had that block indexed on a cnc with bronze bushings for perfect alignment of the lifters. I kept the first cam and lifters in order that I took out, because the lifters didnt have a scratch on them. The car was 3500 with me in it and had a tremec 5spd. Best time was a 10.86 at 127.96. Not to bad for 87 octane and letting of the gas three times down the track to be easy on the drivetrain. Going through at 6300 rpm with a 28 tire and 4.11 gear. This new motor should get me a low 10 at least with alot of clutch and firm shifts. Thanks
