Frustrating day
#1
Yesterday i got my block and rods etc. back from the machine shop, they did all the work including hone,bore, and install cam bearings. I began to install the motor this morning and everything went smooth as can be. Did the rods, pistons, crank, bearings etc. when i went to install my camshaft i found out that my new cam won't go into the last bearing. i tried to spin it and everything and it wouldnt spin or go any further. i thought i would try putting in the old cam i had and it did the same, so i know it's not the cam. my question is after installing all the bottom end, do i need to take it completley apart to put new cam bearings in it? Any idea what can be done? thanks

No you should be able to change them out or bring back to the machine shop and ask wtf

I would take it back and have them finish the short block. It'll save some headaches and IMO is definitely worth the $$. They may have installed the wrong cam bearing.

They have a tool that presses them in from the cam hole

It is possible the bearing is either mushroomed slightly from installation or cocked in the bore.

+1 to that..My freinds 350 chev we worked on had a cam bearring cocked a bit ..He ended up having to tap it back in place him self...The company he got the motor from went out of bis before he could install the motor..So no way to get anyone to fix it but us..lol

Yep, that's my guess. They can remove the pesky bearing without bothering the bottom end. Again, I'd take the cam, timing chain and gear, and timing cover and have them do all that before you bring her back home.
