thanks, i have seen them

while rifling through the case i found a note that i had written velocity numbers on and given the paper i know it came from my machinist friend so i must have gotten the numbers from his mic (i think it came from Goodson)

the velocities on the note are as follows

Nickle chevy .17585

SBC-BBC .19055

BOP/AMC/GM V6 .18732

Ford .18510

there were no velocities for chrysler (but i did write chrysler under nickle chevy) but the number i'm finding closest while calibrating this particular mic for chrysler is .19330

it's been so long since i wrote the note i'm not sure if the nickle chevy velocity was intended to be used for chrysler as well but what i'm finding is considerably different

now i don't know if these velocities are mic specific (they may well be) and what i found with this mic is you can't set a specific exact velocity it changes in increments of .00153 which equates to a .001" change in the reading
