340 Static Compression Numbers and Test Procedure

92b said
Since we're already in the weeds here's my two cents. Pictured is a 360 mopar and 350 chevy crank. It appears the standard ( if there is one) is to line the keyway up with the crank pin. The timing marks are probably placed where it is convenient to get a line of sight ( right or left side ,etc.). Then the balancer is marked accordingly.

wow thanks 92b! Interesting. This all must be a compatibility issue for both design, manufacturing and usage the fact that they standardized the timing mark location on all the LA motors. Also therefore nothing magical about the 6 degree location.
