Put it up on centers with a degree wheel and a dial indicator.
Draw a graph of the intake and exhaust lobe.
Then the fun begins hunting down a spec that match yours.

No doubt a radical track cam for sure .

385 and 305 seems to be a very strange split. never heard of a grind that had that much variance between intake and exhaust lift. Pete might know something. most i've seen is winfields that had around .020 difference

I 'll check it again , after I have cleaned it a little more .

I can't get a good read on these worn out Helios mics. I think its will be better measured in an engine . later!

I have an old block that I have set up to degree my cams.

That is the way to do it , I am in the process of moving my plunder and all my parts are in warehouses and steel shipping containers , I have a block on the stand in the process of dis- assembling , when I get to the place I will set the cam in it , I found another cam with 355 lift int. and exh. not hardly used , I am thinking may be a Schneider grind ? I have about twenty plus different cams to sort out .

I think potvin had some grinds in that mid 350's range as well.

Think about this. It is a used cam, quite worn and an oddball. It will need to be reground to reuse it. Good luck finding someone to regrind it.
Make a lamp out of it. Camshaft lamps are big sellers right now.

Good idea Pete, I have a used 400jr, that would make a nice one.
