All the torque was available at... idle. (290 ft. lbs. if I recall)
***EDIT*** I keep saying when the car falls apart the engine is going in my bolt.

They're also very hard to find stock parts for, and speed parts are just about nonexistent. The 390 is a very good engine, but the newest ones are 1962 models- - - - -pretty old for a daily driver. The 429, 472 and 500 engines are very powerful, still pretty plentiful, and only slightly heavier than a Chevy small block engine. I've got a 472 and a 500 that will find their way into project trucks before too long.
