Lifter Offset

[WyattV8]

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.

I was really just trying to illustrate my assumptions on the way things line up... I spent maybe a minute on the thing.

So what I'm hearing is that the lifters sit directly on the cam and are not designed to contact the cam in this form?

I'd be really surprised if that is how the bores are setup. My assumption would be that the lifter bores are on the same exact centerline as the camshaft. Offsetting the lifters would make grinding a cam a bitch.

we have off set lifters in one of our comp motors the lifters set in the bore just like any other lifter would what is off set is the top of the lifter where the push rod sets. on one side of our motor they are offset all the way to the back on the other side they are offset all the way to the front. we had to do this to clear the intake runners cause we moved them so much.

keep in mind when you offset the lifter you have to off set the rocker arm as well... looks kind of like a dog leg if you will.
