Shovelhead 19t eng to 22t eng sprocket what size primary chain needed

[Downtown Cowtown]

69 shovel rebuilt after piston hole,ive run a 19t eng sprocket for 40 yrs going to 22t to get more top end or so s i think but what length size primary chain is needed ???

80 82 thought i had a 80 in the bike but counted side plates an had 36 so s ya double that an get 72 maybe Mr jack can chime in he knows theses trouble heads

22t is what ole pan sidecar ran i think for gearing i dont run a compensator

thinking 22 will pull my 1000 lbs an a bit ok, since side car rigs run 1050lbs

ive called the shops and searched the net, no info on length of chain to date, thanks

69 shovel, 60 over wiseco pistions
