Rusty, it took a while to dig up my info. The work order back around 1990 said R-4452761 DC, the stock #P3412044 (276 and .460 lift. (Manual)
DC Purple shaft P3690213 (268 and .450 lift) Stock #2899206 (auto)
Not sure of the odd # on the work order, but it was a Purple DC. I did have the box the cam came in until 4 years ago when tossed out in my move, with the original cam in it.
