Cam change question.
Is it possible to have the CAM changed while the engine is in the car?
Or does the engine have to come out?
A Shop quoted me 14hrs labour to change a CAM. Almost $900 :eek:
Is that realistic??

Re: Cam change question. (MrNuke)
It can be done with the engine in the car, but its back breaking work
( or it was for me ! )
I did heads and cam and it took me a lot longer than 14 hrs, but i took my time and i had not done a Vette before.
I would want 2 days to do a cam if i did it again because of all the little things that go wrong along the way.
If they are familiar with Vettes and have all the right gear 14 hrs is probably on the safe side i guess
:cheers:

Re: (scorp508)
If you are going to do the cam change, mind as well do the head to. Cause its already off. Dealer charge a flat rate of 14hr. The mechanic may do it for 6hr. But you still have to pay 14hrs.

Re: Cam change question. (MrNuke)
Fairly old guy answer.
Years ago the we would worry about cam bearing wear and set to the existing cam. So every cam change required a block removal (if you wanted it to last and maintain oil pressure); cam bearing removal and cam bearing surface bore align; then press new cam bearings fit to the new cam; then new cam.
Now-a-days seems like everybody can just slide a cam in and run for a long time. Figure this is due to modern lubricants and lack of wear on the cam bearings. Not sure what I would do personally at this point, probably just slide in a cam. However I know that a cam that is fit properly and riding on the correct bearing tollerance will help with oil pressure and lubrication in the entire engine.
It's more then just sliding it in, but not quite sure how much!
