‘66 Barracuda
Welcome to FABO. Early A bodies are fun cars and I think are pretty cool no matter what is under the hood. You have a 273-2 barrel which isn't a bad engine. Now, if you want more performance you could hot rod what you have or install a 318/340/360. You can use the existing transmission but if you only have a 7 1/4" rear end you may want to upgrade that to a 8 1/4, 8 3/4, or a modified Ford rear. Along with that swap you may get big bolt pattern wheels.
