Slightly used, no more than 2k mi before this motor broke a valve and I did not re-use the cam in the new motor. Took this Cam to the machine shop to have it polished for re-sale and they told me it did not need polishing, it checked out A-ok. This unit has the long dowel pin and deep center-hole so it should work for all makes/models of LT1's. If you have an OBD1 car, simply cut the dowel pin or replace it with a shorter one.

If you are not familiar with the GTP6, it's Craig Gallant's custom grind that's similar to a 306 Cam but it is not as hard on the valve train as he tweaked the ramp rate to close the valves more gracefully (as it was explained to me by Craig). Specs are as follows:

Duration @ 0.50" 235/242 Lobe C/L 355/370 with 112 deg CL. Translates to 568/592 with 1.6RR.

Unfortunately I did not dyno the motor with this cam and only had a couple passes on street tires at the strip but with horrible launches (due to tire spin) on a full weight car it ran in the 12's at 112mph prior to much custom computer tuning.

The cam's powerband is roughly from 2500-7000rpm. Progressive power gain from about 1000rpm idle up to 3k rpm and at 3 it comes on hard and strong. Pulled hard for me up until around 6500 and tapered off but that was mostly due to tune and rocker stud flex, etc. Should taper off at 7k and allow you another 500rpm beyond that of decent power.

This cam was close to $400 new, custom ground by Elgin Cams here in CA, not some poor quality overseas unit. Would like to get $250 for it or best offer.

Thx!
