Anyone install a Milodon 13000 gear dive on a 60mm Cam? I'm currently attempting, and the thrust bearing supplied only contacts the block about 1/8" of an inch. Searched high and low and there doesn't seem to be wider options. So just wondering if its a concern or not.

Thanks

If Milodon doesn't have a solution then you'll have to engineer your own solution.

Looking at it more today, I centered the lobes under the lifter bores and the cam would need to move about 3/8" rearward to allow the bearing to contact the block. I'm thinking the boss maybe was cut back to accommodate this and not need a bearing.
Going to make some phone calls tomorrow and find out.

Man that is massive core shift,, are you sure it will work fine for you shruggy work scope twocents
I would at least check #1 and #6 cam timing in relation to TDC to make sure their is absolutely no differences in the cam timing on the passenger side from the drivers side

so that block casting allows for a raised cam option?


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I personally don't like the limited surface contact FWIW. You may have to source a bronze bushing, no harm. ALSO, it doesn't appear the cam is piloted now with what you have going? From what I have seen the depth of the undercut on cams bigger than OEM diameter is cut as-if you were just putting a timing chain on it. I've had to lathe a couple of 3 cams on the front undercut deeper to get the stack-up correct for my Jesel belt.

Yes that is for raised cam..

That's not core shift.

I was thinking the same on the bronze bushing if needed, those I can find w/ proper ID/OD. What do you mean by piloted? Sorry I'm used to small blocks. Thanks
