here ya go

100 shot I would say would be max. Yes there are a small amount of sealing issues but has not really been a problem. No blue smoke but it does use a smal amount of oil.

Thanks. One of them quoted for my car(427) was 238/244, 114 +3. Lift .629/.629. I want to shift in the 6500-6600rpm range so I was thinking of going with that one. Just trying to get a feel for it.

Thanks for the information. I don't think my 427 will be that potent. Interesting that the cams are similiar. Your motor is putting down some power.
