What Vendor can drill and cross drill camshafts for internal lubricaiton (center lube

[P911S]

Hi engine builders, do you know of anyone that can modify camshafts to have center lube cams? Webcam said they've had a few customers use a gun shop to bore it and then another shop to do the cross drill, but is there anyone abroad that does this or a more efficient way?

Why do you think you need your cams drilled?

If Porsche abandoned this technique decades ago.....

I don't who does it. Just asking an honest question.

What you are looking for is a machine shop that does gun drilling.
Cold cast is relatively soft so you won't need special tooling.

I would like to know who can perform this drilling also. My car has Solex center lube cams that are NLA from,Porsche.

The team at WebCam knows a source that can gun drill. I didn't ask for the source since I found some cams pre-drilled. If you're interested call them and they'll give you their machinist that's local in SoCal.

Cold cast is soft but drill bits can wander a bit compared to other metals. Edm would be a better choice.
