stock distributor curve

[sleeper bird]

does anyone know the stock distributor curve on a 66 with the 428?iv been having a timing issue and bought a replacement distributor and would like to make sure the curve is close to stock.

ok well i found out why there were no replys,i looked in my handy dandy service manual and realized there were several distributors with different part numbers and different advance curves.my car has the thermactor system but i gutted the pump and plugged all of the lines so basically its there but not functional,i guess ill get the part numbers off of the original dist and compare that to the 428 without the thermactor.
