1969 Race Dart w/ 426 Hemi- garaged for 45+ years

I don't know enough to get it running. FIL's friend said there are some radical race parts in it and not meant for the street. Also like I said I don't know how it was put away. I didn't want to hurt anything internally. I am looking into Hemi builders to tear apart and rebuild to put it back in the car.
Hey man this is VERY COOL!! One word of caution is that do not advertise too much to the "HEMI" experts that you don't know what you're looking at or doing. That's a sure fire way to get taken advantage of by the devilish "Hemi aficionados" of the universe. I would pull in a long time trusty friend to help you disassemble the engine yourself so that you at least know what is inside the engine before you drop it off. You can' hurt the engine by taking it apart your self as long as you retain that same cadence of "baggin' and taggin'". Take plenty of pics and then drop it off.
