I think that unless you are going to run your engine at the salt flats at very high rpms, that Henry's C crank , even drilled correctly for full oil pressure, is as good as WE have it right now. I will add that I have a C drilled crank in my present B short block build, that used to live at Bonneville, until the rear flange was snapped off of the crank. The crank was welded with new flange and I'm pleased to be able to use it again. Those boys that run at the salt use these A/B engines harder than any of us guys will. Hope this helps you out in your thinking. Of course if you are set on A sized rod throws, you can have the full sized B throws cut down..lol

SCAT makes a counterbalanced Model A crank with the correct 1.625" main journals; http://www.scatcrankshafts.com/produ...e/crankshafts/

You are correct regarding the scat A crank.
1929 did not mention whether he wanted an A or B crank. He wanted counterweights and my mind went right to model B/C cranks with integral counterweights, because that's what I use. I figured that maybe 1929 did not know of this counterweighted crank. That said, if you want a scat to install in a B block, then I stand on what I wrote regarding that crank having B size mains and A size rod throws.

You both likely already know this but it might be worth saying for those who don't, ....SCAT will machine a crankshaft to whatever specs you choose to order. The additional cost(s) are only proportional to the additional time it takes to make the changes.
