Eliminate Cap Walk

Cap walk is a cause of lost oil pressure and engine failure. Under extreme loads insufficient main cap contact and clamping load can combine to crate cap walk and engine failure.

Combined with the multiple register points and the highest clamping load of all aftermarket blocks Keith Black main caps by design have full cap to block mating surface contact. Well understood fact that friction and interference are more effective locating features than a dowel, Keith Black combines both to completely eliminate the risk of cap walk - a well known issue with Chrysler RB block design.
