73 340 crankshaft p n ?

hi
what is the corect casting no for a 73 340 crankshaft ?

thank you !

I don't know the number but it is the same casting number as a '73 318 crank but is balanced for a 340.

The correct casting number is any one that gets you a 4" stroke!

I assume you want the casting numbers, not the part number.
