CAM HELP NEEDED!
Hughes prides themselves on using "REAL CHRYSLER" fast-ramp cams (high lift for a given duration) which do give more performance but at the cost of valvetrain longevity (mainly springs and lifters). A buddy of mine used one of their hydraulic flat-tappet cams in the SBM in his Ramcharger truck and it ate a lifter once during break-in and then again about a year after break-in. He followed Hughes' instructions to a T and when he called them for a replacement the second time it went bad they basically told him it was his fault and to go pound sand. I personally wouldn't buy anything from them unless you don't mind having no customer service. Plenty of other horror stories if you search around a bit.
Better IMO to call up one of the smaller outfits like Schneider, Bullet, Racer Brown etc. and get something from them. Or pretty much anyone besides Hughes.
