I have a custom ground cam that I bought off somebody else with no paperwork on it. How would I go about finding what ICL to set it for? I don't even know what manufacturer it came from. It's a hyd roller, 230/[email protected] and a 110 LSA.

Robert, how much traction do you have?

If you have drag radials and a good suspension, I'd install the cam advanced 4.

With so-so traction maybe +2 or straight up.

With poor traction I'd go straight up, possibly even retarded 2.

I haven't run this cam before so I'm not sure what kind of traction issues I'm going to have. I guess I'll just check it and, what's the rule of thumb?, set it 4-6 degrees less than the LSA?

Rule of thumb is to install it straight up for the most part, and I wouldn't advise doing anything but without knowing what the specs are. Without the specs, you can't even choose springs, so it's pretty worthless until you know for sure what it is.

The cam should have a number on it on the rear, and possibly a work order number. Some hand grind the work order number into them. Post that number, someone should be able to ID the make, and with the work order number, you can call the manufacturer and find out what the grind is.

Otherwise, you can add it to that grinder stand.
