I'm hunting a 307 crank. Anybody have one in good shape that are willing to part with?

i have a good one. Crank is free. $50 to take it out & box it plus shipping. You can probably find one cheaper & closer....Zoomy

You building a large journal 327?

No sir. I am gonna build a true hybrid. Its a 400 block with a 307/327 crank. The displacement comes out to 352 if memory is right. I also race dirt tracks. With this type of motor I should be able to gear it real high (or real low I guess you would say) and turn the rpms. I have run a 377 ( 350 crank in a 400) in the past and liked it alot. These type of motors are soft on low end torque. It makes it easier to NOT blow the tires coming off the corners.

Zoomy, I may be in touch soon, thanks for the offer.

I have one in south Texas. Just sitting in my storeroom. If you come and get it its free. I also have good pistons and conecting rods. I'll let you have to. All from a balanced and blueprinted 307.

Here you go.... Seems like a neat build. I was considering it at one point.
