Cam upgrade
For those that have done a cam up grade did you change out the plastic breather gear? If so did you replace with Jim's or S&S?
I have a 97 HD RK and I'm going with a Andrews EV27, Andrews chromoly adjustable pushrods, Fueling lifters and Torrington cam bearing.
I've done a lot of research on this and one Indy out of three recommended changing out the plastic breather gear. Should I or is the one Indy trying to make an extra buck? He quoted the Jim's breather gear at $110.
Any input would be much appreciated.

Very good question ., havent seen a lot of posts about this but i am also about to do a top end and cam chest rebuild. Your listed parts choise seems to be about the same as mine but in regards to the breather gear , i plan to change out the plastic gear and go with an aftermarket . My reasoning is simply considering the age of the motors we are working on here. Plastic is great stuff but it dosent stand up well to age , heat cycles , etc. For the extra bucks involved and the potential damage a failed plastic gear can do to a newly refurbished motor , i will spend a few more bucks for piece of mind .

Couple schools of thought on this one, the plastic breather can pick up metal shards that then get embedded in the plastic and continually gouge the case as it spins. or- The metal aftermarket breathers are harder metal than the cases and if anything goes wrong the cases suffer big time...
My choice is stay with the plastic, just get a new one, they are cheep, seem to hold up and you don't have to mess with re-shimming if you stay with the same type.

Edster, I have seen this one and as Doug stated it seems to be a "personal" question, will the metal do more damage in event of failure? See you live in T.O did you try Heavy Duty? I am also looking at the fueling lifters have also considered the SE why did you choose the fueling?
