340 Info

[Demonracer]

OK guys and gals, I need some information on a 340 I've found. The casting number on the block is 2780930, and the casting date is 5-26-72. I need to know is it a cast crank, or steel crank engine. It is a standard bore, as there are no over bore numbers on the pistons. The current owner doesn't comprehend how to tell the difference between the cast and steel crank. All help is greatly appreciated.

Thanks,

Bill S.

No balancer...

Does the flywheel or flexplate have weights on it?

May 72 casting date on a 340 should be a cast crank.

Does the flywheel or flexplate have weights on it?

from the factory....weights would be on the converter not the flexplate.....and the flywheel would be drilled to balanced ..

Sorry I wasn't clearer, it is just a short block with no balancer and no flex plate or converter. But as 6pak said, it's probably a cast crank motor because of the date. Thanks for all the info.
