I got the 39mm FCR and love it. Huge power gain on my 440. I don't know about a .40 piston, correct me if I am wrong but does that make it 406? You should see a difference with a larger carb, but you will get bigger gains if you do all the engine work first. Such as valves, port and polish, high flow air filter and exhaust.
Either way good luck.
