A trick I learn many years ago was to take the firing order divide it in half
and put the last half directly under the first half. This will give you the
pistons that are opposite of each other. To tell if number one is top dead
center on compression then do this.
1243
12
43
now turn the engine till number 4 valves are in position that when the engine
is rocked back and forth the two valves on number 4 will close and open, the
valves on number 1 will not move. You can actually find top dead center
without looking at the marks on the flywheel or the pully up front. where ever they
are on your engine. The same thing will work on any engine from 2 to 16
cylinders that uses standard piston order. This is real handy for installing a mag
or dist.
