Lifter bushing oil hole size

I have found that "Cowboy from Hell" prettymuch knows anything you would ever need to know about motors. He posted a very long article on how to build a high HP reliable street motor, it included detailed instructions on plugging and drilling oil passages. I looked for the post but could'nt find it. I suggest you contact him and hopefully he will hook you up with all the build info you need.Good luck with your build.

All respect to Cowboy. I found the post explaining the build..

Sticky #3: Guidance for 351C Engine Building

Sticky #4: 351C lubrication system

Whem I built my 351c a few montha ago I was told by both Cowboy from Hell and Denny to make the hole the same size as the hole in the side of the lifers or slightly larger. Thats what I did.

The Crane roller lifters I have in storage have two 0.060" holes on the side. That would be equivalent to one hole 0.084".

So I would drill the bushing 0.084" or as close as I could get to that.

If you custom order a set of 5/16" push rods made of tubing with 0.120" thick walls, the 0.072" hole up the middle of the push rod will serve as a nice restriction to the flow of oil to the valve gear, downstream of the lifter.

I hope you've found Denny's kit easy to use.

If you click on the 351C technical info link in my signature line below, you'll find another resource for 351C info. A work in progress.
