I'm building this 58 to be a mostly street/ show truck but i love to play in the mud. i drive this every day just about. highway and country roads muddy a$$ job sites and on the farm. i'm not skeerd to actually use it as a truck. 85 k5 frame sbc 406, 428 hp @5000 525 torque @ 3800 built th350 manual/auto, 208.ordering a tuff country 6" susp lift (for its soft ride) i just got a corp 14bff 4.56 open carrier.and 37x13.5x16mt baja claw radials. lookin for a 60. anyway i have 10 bolts 3.73 and 31's. the engine has so much torque if i tromp on it it just breaks loose and spins.even goin like 35-40. i love to hot rod this thing so i think i want to lock the 14bff (so i can spin both ha ha) but heard that lockers ie. detroit etc, are noisy and seriously effect the driveability of the vehicle.let me hear what you guys think. is a locker the same concept as a posi?
