Dear 1984:

If what you want is more power per cubic inch then the objective is really "how to cram as much air into the combustion chamber as possible". You are correct in trying assisted intake or turbo/super charging. You can also add nitrous for momentary superpower.

However, better buy a broom and a dustpan because these motors were built for standard service not racing.

One other item is that the flathead motor is restricted as far as available valve lift. Overhead motors can have lots of valve lift whereas L heads will smash into the cylinder head. Thus, super/turbo charging is the only efficient means to increase the charge.

Hope this helps.
