Before you do anything you need to find a copy of the Street Rodder series on the 394. I believe they used a 400 chevy piston and some bigblock chevy type rods with an offset ground crank. That did three things: Got more cubic inches, saved weight in the reciprocating assembly, and allowed the use of easily available and less expensive aftermarket high performance parts.
I really believe it's worth your while.

Web search results, "The guy who built the bottom end (short block) with Doc is Kerm and can be reached at 717 334-6882 most any weekday. He can tell you anything you want to know about that engine build. He's a lifelong Rocketeer! He's sold his shop to his son in law, but still has a bay there where he works on projects that interest him.
The shop is K.A.R.S. in Gettysburg, PA."
