Coyote engines what are they worth

[evoinit]

Instead of a 16 mustang which I put a deposit on
Should I buy a 12 and sell the motor towards a better one
Or build the stock one
I want a 9sec car that I can drive comfortably

I sold a few so far bone stock with all sensors and intake to pan for around 4000$ plus or minus a few hundo depending on miles
