13068 326 271 190 0.400 114 LSA The HUC Series Hydraulic Rollers are very smooth designs intended for high RPM use with heavy valves. These are very similar to the Xtreme Marine high lift lobe series, but may be slightly more stable. .

Wow, one has too wonder what that sucker in! Take some big cubes (500 +) big heads and a ton of compression to make that work, then to run good it still probably needs a 200 shot of NOS. LOL
The cam the 461 in my TA is ground close to that, except 18* smaller than that one, also a marine type grind on a 114LSA and has .632” lift. My engine tq peak is right around 5000! The power band goes to 7000. That one makes my cam look small. |

What would you use that cam in ? One example....
I'm not at Liberty to provide exact details but I can say that years ago Ken Keefer (aka Pontiac Dude) used a similar hydraulic roller cam in his 535 cubic inch pump gas combination. He used a Comp Xtreme Marine High Lift lobe with similar .050" duration on the intake. Edelbrock cylinder heads, basic clean up. If memory serves me right about 300 cfm. Pontiacs in the Park. VMP 2008. Heads up Streetcar Shootout. 73 pills in a Big Shot plate. Stock suspension 3450 lbs. Hydraulic Roller AND Pump gas. 9.30@144 http://www.youtube.com/watch?v=BMFWOYr6VSE .

HA! I was pretty close on the application!
Steve I’d say your memory is in good shape if you can pull that combination out from memory

I've got the same cam and it works good in a 400 and 455.
It's in the motor in my 57-wagon now. GT |

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.
