Getting Lucky

I did that at a plumbing warehouse, went back about 2 weeks later, the parts man I like to deal with kept it for me.

Yup, don't know what it is. Every year around my wife's birthday I have to look it up, just to be sure. A couple days ago on Mother's day I had to dig out the wife's birth certificate just to be sure I had her name right. This morning I found the coffee I was supposed to have with my dinner last night, still in the Microwave.

All that being said, how come I can still remember most of the clearances and torque specs for a '68 396?
