The piston stop is used to find true TDC when
degreeing a cam
If I remember corectly it was like 2 1/2 or 3"
I have reg piston stops but this is a way to
save a few bucks
The center line is 114/110 I found that setting
them at 112 works great realy helps the low end
I have the fed mogal cam set at 111 the center
line is 112/112 on this cam just be sure you
set your injector sync at the least +3 I have
mine at +6

All is good, I found a Snap On truck today and bought a TDC indicator, I think I like that better than a stop.

well that will get you close
using a stop will get the true TDC with a degree
wheel
The crank will move a few degrees either way and
still show TDC the only way to find the true is
with a stop from both directions
even a dial indicater will be off
Degreeing the cam is not nessasary, mostly used
when your using a HP cam or changing the center
line for a reason
But not a bad idea I have found in all motors
a few degrees off these days with computer
controled digital readout machines the parts
have better accuracy in the old days it was done
with fictures and human eyes so thiks have gotten
better
When I installed the last cam I did in my truck
a fed mogal cam, cloyes street roller chain and
gears it was right on the money at 111 the cam
center was 112 after the initial chain streach
It will be dead on
In the older days mis matching manufactuers and
parts you always had to check them and 95% of the
time they were off 2 to 4 degrees
