Default Cam Timing

I have the Cam and Crank gears lined up with the dots facing each other. I know this means #1 cylinder is at TDC. IS #1 pistion at TDC on the firing or exhaust stroke?

I think it is TDC firing, but you can easily verify that by rotating the crank and watching the valves.

Dots together = #1 and #6 are both at TDC. #6 is TDC firing position and #1 is at TDC exhaust position.

I think all you have to do is , add the balencer and turn it 180 degrees and it will line up the zero and the timing tab and that will be #1 TDC and ready to drop the dist in on the #1 plug wire.
I just did this about 2 weeks ago.

Hey guys, does this rule work for big blocks also? Seems like it would.

Close but no cigar for you!

Rotate the crank 360 degrees (not 180 degrees) and drop in the distributor so it points to #1. Then you are good to go.

YOU'RE RIGHT ! 360 - one full turn .... 180 would only be a half !
