I tried posting this in the Q&A section and had limited response so I thought I'd try it here.

I was considering one of the OC Billet cranks but was wonder how folks are mounting their flexplate without the locating flange? Or is everyone running a non-torqueflite trans (JW makes a GM adapter)?

Thanks in advance and Happy Thanksgiving!

I saw your other posts on this, I bought a adapter ring from Kieth Black Enterprizes, 562-869-1518, not the piston company To use on a old 8 bolt top fuel crank, there the 392 hemi 8 bolt type cranks, not 426 hemi type It presses into the crank and locates the converter hub perfectly, not much money either Don't forgot that the distance from the flywheel mounting flange to the thrust surface of the cranksahft thrust bearing is different on the top fuel cranks like your wanting to use and the stock street hemi cranks,I think the top fuel cranks flanges are 3/8 thick and the 426 stock crank flanges are 1/4 inch thick, or close to that You'll need to make sure the converter to pump hub depth is correct, you may need a spacer plate or have the converter machined to match your crank and block I attached a picture of the adapter ring

Why would you buy a crank that isn't designed for your application? If you need to run a flexplate then buy a crankshaft with the correct flange on it. There are plenty of cranks available these days, no reason to mix and match the wrong parts.

In my case there really aren't that many new billet cranks out there for my application (especially in the stock stroke length) for $1800.

I have spoken to some GM guy who have run the Ohio Crankshaft crank without any issues.

I am open to suggestions, I am looking for a stock stroke crank (3.75) capable of handling 1800 crank hp (turbo not N2O) and was leaning towards a billet. We have had customers making that kind of power on the Callies Dragonslayers but I think that is pushing the limits and am hesitant on going that route.

Thoughts?

i'd rather sell you a Callies Magnum series over the dragonslayer for your application. it's a little bit more money, but it'll get the job done nicely and much better than the dragonslayer series for the Mopar application.

Shouldn't be hard to find a crank that will handle that power level. Call a few of the Mopar engine builders who are familiar with that stuff and get some recommendations. Best Machine, Koffel, Indy, Barton, etc. I doubt that any of those guys will recommend an Ohio crankshaft.
