In case my previous post was not clear. Do not worry about the crankshaft. The stock one will be fine.

Use a 1954 359 cu in straight eight. Blueprint the bottom end and install forged pistons. Keep the revs down to 5000 RPM or less.

15 pounds boost should give you 400HP. The problem will be dissipating the heat through a cooling system designed for 1/2 that power level.

Pay attention to the cooling system, install a new aluminum head, and do not use full power too long at one time and it should work great.

A Paxton or Vortec type of centrifugal blower will work the best for what you want. They make up for the flathead's restricted breathing at high RPMS without overdoing it at low RPMS. They have the least parasitic drag. And are the easiest to fit.

Would also recommend heavy duty valves, exhaust valve seats, and a cam made for the application.

You will need to make up a header. A stock intake may be OK but convert to port injection.

If you use a Megasquirt system you can have crank triggered ignition too. Otherwise, electronic ignition and an MSD box.

Should be quite a ride.
