Doing high tech modifications to these glorified tractor engines with 1920s design features is sort of a "lipstick on a pig" approach. No matter how sophisticated the peripherals are, we're still dealing with an antique. That would include pressurized intake systems- - - -turbo or mechanical boost- - - -and fancy headers, dual exhausts, etc. Unless the base engine and/or cylinder head is upgraded in the process, the primary purpose of the whole procedure will be to impress people who don't know any better. The actual gain will be minuscule, but the alleged engine builder will be able to brag about his "accomplishments" on some website without providing any dyno figures to back up his claims. I'd suggest adding a billet crankshaft, forged pistons, H beam connecting rods, and a main bearing girdle to the build, along with a 12 port cylinder head- - - - -then post dyno run figures to back up your claims.
That will impress me.
