Crank stroke before 49

[3W Hank]

I found many 3.75 std size cranks here in Sweden ( cheap ) as no one need them and I has a Berco RTM 225 crankgrinder.
I like the idea with a 1/8 baby stroke and the 2" rods and std 3.75 C-H pistons ( just for historic ideas how it could been done ) but Tim, I will go Ross ofcourse.
But in the Weiand/stock heads engine I could go Jahns if I found them, as it will be more just a good look shop office engine.
My focus is on the race engine Merc 41 block set-up.
