Best 340 stroker kit?

I'm in the market for a stroker kit for my 340. Who makes a good all inclusive kit that is ready to drop in? I have a good set of worked W2s for it and it's going into a 72 Duster that will see mostly street duty and showing off at cruise-ins with the occasional pass on the 1/4. Hughes, Mancini, Muscle Motors,.....? Who's the best?
