Great input thanks. A 30 lb steel flywheel might be a great compromise to suggest to the builder.

Keith Craft is putting together the motor and I am planning to have him get the clutch and flywheel and balance with the motor. He's use to people asking for aluminum flywheels, but then he builds some mega-HP motors for a lot of them.

Mine will have a 4.25 inch stroke, somewhere between 9 - 9.5 compression and he was thinking a 222 to 232 duration cam when we talked. I'm using a 3.31 rear and WR toploader. This is a street replica build and not a sunday race car so I'm interested in a smooth off-idle, first gear starts and reasonable driveability.

I know, I know - no overdrive 5 speed. I'm old school. I wouldn't know what to do with if the engine wasn't buzzying along on the highway somewhere around the crest of the torque curve. Believe me - this is going to be worlds better than my 427 Vette with 4.11 gears.
