my car was originally a sprint ohc six pwr disc brakes,am radio,4bbl,rear defrost,3 spd heavy duty manual,manual steering,3.55 safety track.it had someother options but i cant remember them off the top of my head.if it still had the ohc when i got it would probably still have it and i would have found another bird to hotrod and leave this one as is.the sprint six is a pretty cool powerplant very high tech for its time.
