Hello all,
I spoke with the shop earlier today and asked advice regarding my cam bearing prep on my 345 (79 Scout II) rebuild. They suggested posting here to the resident experts. Just so I don't misrepresent, I have been writing the build up on bp to document the decisions I'm making (stinky rebuild thread), but am coming here for specific advice on the cam bearings. I appreciate the deep knowledge that resides here. I am new to engine building. I started this project a year ago with a different motor and tabled it for my newer block that I'm now working on.
Per the mayben sonja motor build thread (post 22 of that thread), I decided to notch the rear-most cam bearing to expose the lateral oil feeds to the lifter galleys. I think I overdid it. With the cam sitting in what I believe to be anatomic position, the central, circumferential groove of the last journal is visible at my notch. I'm afraid I May have too little restriction here and my oil pressure to the other cam journals will drop. I welcome advice as to whether this bearing needs to be replaced. It is a brand new durabond bearing talking with a brand new isky cam.
Here is an image of my not-so-handywork:
Have I gone too far?
Thank you very much, jack
