Personaly I'm not a cam expert, I just provide good solid proven information for conversation around the coffee table from many who are experts. Like Cliff has and does. Take it or leave it

And in my opinion look at catalogs for interest and ideas, when the time comes it's easy to call a cam designer and discuss it with them. If necessary purchase a custom cam suited for your needs... not just a catalog number !

For those interested and are not aware the Old UltraDyne lobes are available today at Bullet Racing. Excellent cams and good people to deal with. They do custom cams, any intake lobe, any exhaust lobe and any desired lobe separation... be it 110 or a 112 LS.

On my 505 I removed my first Crower solid roller cam and replaced it with a custom UltraDyne MSP solid roller from Bullet, it had 3 degrees less intake duation and a bit more valve lift, and with the same 110 LS. I picked up about 20 hp on the dyno.... thanks Bullet !

For Voodoo lobes go to Lunati. They can do custom cams as well. Note if the Lunati catalog states a certain cam with a 110 lobe separation and you want it in a 112 LS, they will do it. You can order it custom direct from Lunati and I suspect even thru some place like Summit. If ordered thru Summit or others the cam will probably be shipped directly from the manufacture to you.

The voodoo cams listed in the 'Pontiac' section are limited. However if you look at the Small Block Chevy section you will find additional lobes there. The answer, you call Lunati and they will grind a custom cam based on those Chevy lobes on a Pontiac size billet core using the lobes desired. As you see it listed in the sbc section, or maybe with a different exhaust lobe with less duration if desired, or with a 112 lobe separation. Bingo there is your custom Pontiac cam.

Same applies for Comp Cams.
