I used the 246/253 duration cam in my 455 way back when.
That was an awesome grind. Went 12.01 time after time. Heres a quick breakdown: Car weighed 3750 at the time. 455 .030 TRWs. No 13 heads,unported.Just a valve job. Stock T-2 intake. Holley 850. 1.75 Heddman headers. Comp Roller tip rockers. Torque Tech 3" exhaust with tailpipes. Generic TCI 3500 conveter. 3.89 gears. Cam was also advanced 4 degrees. Gave alot of Mustangs the whooping;as that cam was very streetable.I drove that thing everywhere. Mark.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
