As far as the tall decks go in stock form , once you get that 80lb flywheel off of it & get rid of the govenor carb it does pretty good . We put a few of them in 1/2&3/4 ton pickups with good results. Change camshaft and a set ot headers does wonders. Some of them have tiny valves and a
head change really helps. All said they make a great torque motor. Around here you can find them pretty easy [ cental Pa. ]
