I would like to check the actual timing in some of the CAT CDI boxes. What would be the best way/method to check the timing on a sled?

well...

If you get a dial indicator and find TDC of your #1 cylinder and dont move it, and then mark a fixed area on the chassis with a white marker and then mark a white mark say on the primary clutch exactly in line with the mark on the chassis it may give you an idea. However timing curve built in the CDI may be a problem also. My old 73 JDX8 is easily timed, however my 80 Liquifires have a timing advance around 3000 rpms for an idea of issues you may encounter.

Leave it to my buddy Danzig to give a complicated answer.
A timing light is your best bet.

Say Danzig..., how do you time your truck, I wanna be there. LOL.

No kidding Todd...I was trying to attach a pdf. file to my first response, no luck, its not on this computer. Its at work on your computer...

I dont have to time my truck you dufus, its got a gremlin under the hood making adjustments for me.. Go mow your lawn or something, god knows you dont ride sleds on it, so you may as well turn it into a manicured golf course..

Dont give me any crap about working on my sleds in your garage....we arent done yet, once we are done, then you can complain..

Not sure if this really helps any. The 2001 supplement contains some info.

A dial indicator should be used to verify TDC of each cylinder. A crankshaft stroke to degrees of rotation chart should be used to mark the flywheel or primary cluch and engine case or chassis bulkhead with the various degrees (in inches or mm) you expect. Use a automotive timing light to check your marks at various engine rpm's to get an idea of the curve.
