LA cranks

[63SplitWindow]

Are all LA crankshafts interchangeable? Can I use a 340 stroker crank in my 360 block?

 

[Plymouth 65]

No, the main journal diameter is different. 65'

 

[Ottmundr]

No.
And if you do swap around different year cranks within the 273-318-340, make sure you have the right balancer.

Ok.....thanks guys. Been looking for a scat crank for a stroker 360 build and came across a 4" crank for a 340. I will keep looking

You would need bearing spacers to be able to do this. Idk if any are available anymore. Maybe someone has the spacers collecting dust. Kim
