help with cam specs

[70swgr]

I pulled the motor and trans from the dart (360-4sp). I know nothing about the motor except its a '71 block and it runs pretty strong. It has J heads a performer intake and a d/p holley carb. I removed the plug at the rear of the block to ID the cam and found an erson cam w/ 186 stamped over some numbers I couldn't read. Anybody know where I can find specs for this. I tried Erson's web site but saw no mopar cams. thanks, Rick.

P.S. HAPPY HOLIDAYS EVERYONE.
