LS1 cam swap on engine with 65000 miles? bearing safe? My stock engine has 65000 miles on it.
Can I swap out the cam with any kinda margin of safety here? Currently oil pressure is a-ok! 60 psi running, 40 @ idle.
Just wondering if the cam bearings are gonna
**** the bed if I swap out the cam. They have some mileage.
I only ask because that's what happened when i did it on my 1995 Z28 with about 48,000 miles. Just wondering.

Did a search on the life of cam bearings after a cam swap and dug this up. Hoping to get some more replies on this from people with experience on this. I wish this was in the internal section though.
The OP has the same question i have but my car will have about 100k on the clock when i do the swap. Cam will be the torquer v2. FWIW.

I wouldn't even worry about it. The ls1 bearing are really tough and you don't really hear about them failing very often. I vote for just leaving them alone.San Diego Auto Insurance

Okay sounds good. I was just concerned that the bearing's wear would be sped up by the higher stress of a bigger cam because even though the cam is the same size, minus the lobes of course, the worn bearings might wear faster because of the slop in the there between the bearings/engine/cam. Does anybody see what im sayin? It's kinda hard to explain on hear lol

All the cam does is take the stress of opening springs... very little stress/weight compared to the rest of the bearings. You also have to realize that the cam spins at half speed compared to the rest of the motor...
Install it and dont worry about it...
If you are 2000 or below just dont rev it too high or your rod bolts may not like you... I dont know how your cam bearings could have gone bad in your 95 but thats not normal.. maybe whoever installed the cam nicked them up real bad?
