its been a while since I have had the H-balancer off of my 400. do these cranks normally have two keyway grooves cut in them? I need two keyways for the new balancer. thanks

Don't all of them have two half-round keys?? One for the lower timing sprocket and one for the balancer??

I forget it's been so long....

Ed,
Stock cranks only have one woodruff key for the damper. If you are running a blower, your damper probably has 2 keyways, on larger than the other. You will have to get the crankshaft machined for the additional key.
