1996 Cobra engine value ?

[2 cam sam]

I just bought a 1996 Mystic with 76,000 miles . Its runs great and doesn't smoke. I was going to drop in a 2004 Cammed mach 1 engine in it and sell the Bheaded long block. What are these things bringing?

I've seen them anywhere from 1000.00 to 3500.00 in my area you can pick one up for 1500 if your lucky
