I'm pretty sure I'll do this... ^^ and I'm pretty sure the car will go faster than any factory stock 318 2bbl Duster. I firmly believe if you are going to install a 340 cam in a 318, a 4bbl and dual exhaust should by all means be part of the plan. But I'm confident that it would outperform the stock 318 cam if it was left as a 2bbl.
