Your throttlebodies??
Rick,
F&B has a 70 and 72mm TB for your application. for Bone stock 4.7l motors (stock Ram exhaust and air intake) We have seen about 7hp and the same in tq (70mm) with improved driveability off the line and in the midrange. If you add a cold air intake and/or free flow exhaust your gains will increase! We reccomend our 72mm for fairly well modified 4.7s (HO or HO/Comp cams, headers with exhaust reprogrammed PCM etc.). Sorry it took so long to reply... I forgot my login. Cost depends on whose running a sale at the time or not, but list is about 400.00 with sales /jobber pricing running around 375.00. We have a list of distributors on our website (although it needs some updating) that you can check out or you can call us for our latest sale pricing!
