iam wanting to replace my duel point distributor with a locked out electronic distributor and set the timing to 28... i have a 41/2 in crank hub that has one mark at tdc... there are no other marks, was thinking a timing tape, but cant find one for my dia crank hub...does the tape have to be for a specific hub dia? is there any other way of marking the hub?
 
@flathead31coupe ,4.5" dampener. Circumfrence is pi times d. Divide result by 360 to get distance of one degree. Multiply that by the 28 degrees you want.
I came up with a mark 1.099 (roughly) from tdc. Make a mark 1 3/16ths(and a scoshe more) . You will be within a degree either way.
Then, use your advance/retard mark to adjust from there for more or less timing.
Edit: tried to correct the measurment but it didnt take. SHOULD BE 1 3/32.

Lookup "Hillbilly Timing Tape" by crackedback and do that. Much better than timing tape slingin off.

Why are you locking out the timing?

so go from my tdc marh and measure 1 3/32 that should get me close to 28 advance?

Yep. And then i would number stamp that mark 28, so you dont confuse with tdc. My maxwedge damper was done that way (just not by me, and marked at 38°)
