Is the Hemi engine worth more than the car ?

Yes

The early Hemi's don't have the value the later ones do but they are still popular

The car, not popular

Back in the day they would buy Hemi cars on car lot, pull the engine and junk the bodies, so even when they were plentiful the engines were worth more than the car

I would love to have one. Back in 1974 I passed on an early Hemi with 3 speed trans with OD for $100 what a dumb a**

Buddy of mine has a 354 that he got out of a junk yard along with 11 other Hemi's for $25 a piece it is the only one he has left.
