I've had the privilege / pain of working on and with several flatty engines. The most potent 'street' engine was @290+" that was S.C.O.T blown, huge cam, late style Edelbrock aluminum heads, etc, etc. It was in a mid 50's Ford PU mated to a Tremec 5 speed that was very high end. My buddy bought it turn-key and did not like the engine at all. Tended to run on the warm side and according to him - "Didn't RPM at all - like all done by 5200 RPM's"

The guy that built it reportedly spent $18K with H&H flatheads and the engine made just over 300HP - which is a very impressive number for a streetable flat head that needed a little race gas + pump gas for love. Honestly it sounded like not like anything I have ever heard - almost like roller cammed small block - but deeper tone.

Ultimately my buddy traded the entire engine for a 383 SBC even up!! Effin ridiculous really................I was sooo pissed at him - I told him at the time I would have bought it outright and just stowed it away for future projects.
