Here is my restored American LaFrance V12 engine running. It is based on the Lycoming "BB" engine used in Auburn Automobiles 1932-34 This is in the Chassis for my 1932 Brougham
Looks good and sounds sweet! Has a very distinct "aviation" sound to it. I'll bet if you revved it up on a quiet night I could hear it clear down here in Ft. Wayne!
Summers- actually found it about 2 years ago near Grand Rapid in a craigslist ad under "ratrod project" (of all things) ...And it does have a distinct sound to it- hard to describe, kind of like an airplane engine. currently I only have it running on one set of plugs, and I am curious if the exhaust note changes when running two. "Shout-out" to BUBBAS ignition, he rebuilt both distributors and I could not be happier!
