[Tigers] Engine help, 302

[Thomas Witt]

Tom,

Regardless of any advance/retard ground into cams or similar with timing 
chain index points, it is always best to degree in a cam. It helps take the 
mystery out of the "variables."  Although..., when chains stretch, and valve 
lash clearances get altered it kind of throws out the "spot on" aspects.

FYI, I indexed and then measured actual values on a PAW clone of an 
Edelbrock cam.  This is what I got:
Spec-ed 204/.420, - actually measured  208-210/.424 The ramp was so slow 
that the extra degrees likely didn't matter.

Regards, (another) Tom
