WHAT WOULD YOU DO ?

To make a long story short. I had bought a demon that had a 408 in it. I took the motor out & sold the demon. I thought the 408 would be a good motor for my barracuda. Well come to find out it is not a 408. To back up I did hear the motor run & it sounded real good. I took the top half apart. Every thing looks pretty new (that's what I was told) Looks to be stock J heads, double roller chain, flat top pistons. The cam doesn't show any wear. Cylinder walls & tops of pistons look clean. I had bought a small block cross ram intake, linkage & 2 450cfm holley carbs. After doing some measuring of the bore & stroke it is not a 408. Now my question is WHAT WOULD YOU DO put the cross ram intake on & just drive it ? It would be a show not go motor. OR would you sell the cross ram intake, carbs & linkage & put a supercharger or turbo on it. I heard from some guys that one of the past owners of the demon had a turbo on this very same motor. The barracuda will have a 4spd w/ 3:91 gears More street than strip.
