Mexican Superbees

Hey guys I have a Mexican valiant Duster similar to the Valiant Superbee .its a 75 the same as the superbee but only real difference is the badges, engine, and miner details like crome. I bought mines for $800. US. And it currently has a slant six but I'm juicing it up by making it a 4bbl machine. Both intake and Carb.
