Double key post-assembly?

[ytix]

Can a crank snout be double keyed after assembly in a short block?

not that I am aware of

is your crankshaft gear and balancer cut for double keys?

Recent price drop on the FRPP forged shortblocks got me bouncing thoughts around in my head. Hence the double-keying question, but I don't have a short block or the gear/balancer. Thanks for the response.

I had mine done , but it was done while out of the block . How much power are you trying to make ? The only reason I did it was because the Procharger was trying to pull the crank pulley at a angle with the crank pulley being so far out from the front bearing . With a Whipple I would think you would need to be making a hell of allot of HP to need the double key-ways.

I investigated machining my crankshaft for a 2nd keyway at the start of my build. I'm running 15 psi with my Saleen. After discussing it with several shops all agreed at my HP/boost level is wasn't necessary so I abondoned the idea.

At 20 psi I was pulling the crank pulley hard enough to scuff the crank snout from the movement of the crank pulley even with an ARP bolt in there . It was with a Procharger though on an 8 rib with a very tight belt .
