360/380HP magnum crate motor value

Does it have R/T heads on it? Should say on left side of head near exhaust port.

At this point it's a once used magnum motor, taken out, then sat on stand for 18 years. The plus is that M1 intake, performance cam, and possibly R/T heads.

The R/T heads are not as desirable as used aluminum edelbrocks. But more desirable than used bone stock head.

Pluses:

• It's lower? mileage used Magnum motor
• performance cam,
• M1 intake
• R/T heads IF they are on it.
• Known entity: 380hp. Not some combo of parts making unknown HP.

Prospective Buyer Concerns/Issues::

• valve springs loosing rate
• corrosion
• narrow metric rings being stuck
• possible tear down, inspected, new assembly lubed, and re-assembled.
• Lack of build quality from Mopar Performance back in day
• outdated cam specs, (low lift to work with stamped rockers)
• low compression 9:1
• Modern day availability of higher flowing aluminum heads
• no hard proof that motor is currently in running condition
• no hard proof that motor was in running condition when removed. (not calling you a liar. A random buyer knows nothing about you. Nor do you of them)
