The 911-36NT allows for measurements up to 36 inches in length with an accuracy of 0.0001 micron and 0.001 degree of resolution

Comp cams has probably the most extensive line of BBC hydraulic roller and solid roller lobe profiles I have seen. But generally speaking, most of the typical lobes are available from all the big cam companies. Crane, Comp, Lunati, Howards, etc.

Comps endurance specialist is David McCarver. If you're interested in talking to him, I can text you his email address.

My last custom comp billits were very nice however curious about Howard's. The 100.00 difference in billit over cast core I honestly think I spent in beer last night. I'm feeling the pain today trust me.
