Ford 302 Timing Gear Alignment
I've been searching for a while to a question that I think has a simple answer... Hoping someone here can help me quickly.
New timing chain installed with cam sprocket aligned to crankshaft at 6 o'clock (cam) and 12 o'clock (crank). Is that the compression stroke for #1 cylinder or #6 cylinder?
I saw something that said this is #6 compression and in order to get the distributor placed so it's not 180 off, I would want to rotate 180 degrees so that Crank and cam point to 12 o'clock. Is this true?
Thanks for the help!

The cam timing determines everything. You have it set correctly at 6 and 12.
You can turn the crank over 360 degrees, be on the exhaust stroke, reset the timing gears and put it right back on the compression stroke without moving the crank at all.

Ok, yes that makes sense.
In summary,
-The crank is in the same spot every 1 revolution (360 degrees) the Cam is in the same spot every 2 revolutions (720 degrees).
-Cylinder 1 is on the compression stroke when the dots are at 6 and 12 o'clock as described above. This is where I want to be at when the distibutor is dropped in to avoid being 180 degrees off.
-Cylinder 6 is on the compression stroke when the dots are at 12 and 12 as mentioned above. I don't want to be here when I drop the dizzy in.
Others feel free to pitch in because I definitely read the opposite about 2 hours ago on a mustang forum... I think the way described here is correct. Otherwise it would seem that my rebuild book would have been sure to make a point of such an important step.
Thanks 351Cleveland! BTW I'm installing in a 74 F-100 with a C4 and mostly edelbrock components.
