Putting a new cam in my 360

notadart said
It was definitely a concern for me that the lifters I got with the cam had clearly been on the shelf for a while. I lubricated them as carefully as I could, but I never popped them open to look for corrosion/etc. Now that I think I've figured out the source of the issue, I'm less worried about the lifters.

I'm looking at the Lunati Voodoo 262/268. Little shorter duration than the Comp and a higher LSA and more lift. Little less lumpy I guess, but might be jumpier at low RPM?
I just don't know if I can get one in a hurry (and I am in a bit of a hurry).

OK, on the lifters. I did not know what 'old' meant exactly. I agree, probably not any issue here.

With that type of Lunati Voodoo (and I am just guessing which one it is so a PN from you would be nice), I expect it is going to stronger all over. You have a good 9.5 CR (I checked your numbers and got 9.4), so that should make a pretty broad torque curve down low. And the lift is a LOT more, so that will help breathing at the top end. Just be careful on the break-in as these Voodoo's have faster cam lobe ramps, which increases the lifter-to-lobe contact pressures. Make sure you check into your valve spring bind height versus the higher lift, and how close the retainers go to the seals and tops of the valve guides. You have not described your valvetrain parts yet IIRC; that all needs to be right.

Make darned sure that you take the effort to degree the cam!

And reeeeally, reeeeeally make sure the Voodoo skull decals are pasted prominently on the car and post pictures of that....LOL
