This is a set of Motown block SBC engines. From what im told they are dyno time only 406. They made 750 or so on the dyno. They were never installed just pulled of the dyno set on motor stand and have sat in the garage.
What I do know:
Motown Blocks
Alumium Heads
Shaft Rockers
Dominator Carbs
Large QTS oil Pans
MSD Dist
MSD wires

I do not know internals of rotating assembly or head manufacturer. Motors are not being parted out or sold as single unless the offer is very enticing. These motors are not mine only trying to get the word out to help them move. Headers not included with motors.
15500 for the pair of them. Ill do my best to answer what questions you have.
Thanks

Any idea how long they have been sitting?

5/6 years. Have been fogged and rolled over now and again to keep it moving.
