Opinions on this '68 Barracuda
First thing that popped into my head was you said it was built to be a race car......What rear end and gear ratio is in it? If it has something like 4.30s/4.56s it wont be a very friendly cruiser. Also torque converter type and stall speed.
Second, i see the fender tag. I would get a pic or at least the numbers from it. Could add or subtract value depending on how it left the factory?
Third, gotta check for rust.....frame rails, passenger and trunk floors, etc.
