I saw a 55 chevy with a hemi in it and all the chevy guys were upset and I LOVED it.
Your coupe looks Nice. If I bought it I would change out the motor since I have mopar engines laying around. I am fine with what you did in such a short time and the chevy engine doesn't bother me at all since you are the owner of it.
They are easy to sell if the next owner doesn't like it.

Congrat's on the Cool Looking Coupe !!!
