Magnum Swap balancer w/LA timing cover. Marks?

Nuthin to it. remove #1 plug, put the piston stop in. Put the degree wheel on the balancer. I use a piece of coat hanger wire for a pointer. Then, turn the engine by hand until the piston comes up and contacts the piston stop. Record the number the pointer is pointing to. Then rotate the engine back the other way until the piston contacts the stop again. Record that number. Exactly halfway between those two points is true TDC.

Hey Rob, Does he have to pull the rocker arms so the valves don't open and close? The piston stop points towards the exhaust valve and I just bent the living crap outta a Chevy small block exhaust valve a few months ago doing the same thing with a piston stop.
