Does anyone know that dimension?

Well, if the lifter bore is 0.843-0.844" in Diameter, (the lifter itself is 0.700" in diameter) then the measurement you are looking for (radius) is .4125"-.422" or 10.71mm-10.72mm.

So the edge of the lifter bore lines up with the centerline of the cam?Originally Posted by txarkitekt

That would be quite a loose fit, wouldn't it? .143-.144" slop. Are you saying the plunger inside the lifter is .700"?

I'm glad you said that... I knew there was no way that was right.

I don't get it, need help.
Your drawing is goofy, the center line of the lifter bore should intersect with the pivot point or arc center of the cam shaft.
The way it is drawn one bank would be advanced and the other retarded. Or is it I that is retarded?
Are you asking about the rocker arm to lifter bore tilt that the push rod has?

A lifter bore that is out of round and/or has clearances larger than the lifter indicates excessive wear.
Offset lifters are used with head and/or rocker combinations that require the pushrods to be set away from the intake ports or for any other side-to-side clearance issues. The offset has nothing to do with the tie bar in between the lifters. The lifters have offset pushrod seats left or right for the intake and/or exhaust, or any combination needed to gain clearance. -Crane Cams

I was under the impression that the lifters sat "ahead" of the cam center line, that way, the lobe pushed them in a more upward direction instead of relying on the wall of the bore to direct the lifter up. I could be wrong.
I had always assumed everything was in line untill a buddy of mine said otherwise... since then, I haven't been able to check.

Looking at your drawing, the lifter body could possibly make contact with the cam lobe. The lifter bore in the engine block supports the lifter from side-to-side and front-to-back.
