Need help w/gear and slick size on a 402 Duster

I'd go with atleast a 3500-3800 stall converter(if you want the best out there give Ultimate a call) 3.91-4.10 gear and either a m/t 275/60 15 drag radial or 28x9 slick..my 416 ran consistent 11.0's with the above combo..by the way bfg's drag radiald are USELESS...........
