custom.. i make them myself! can barely tell the difference to hasport ..but i can sit my engine how i like it.. i can have it sitting a little lower to clear the bonnet with ease ( and yes i know i'll have to make a custom sump... was going to anyway.. lol
custom sump wont help with ground clearance because your oil pickup and oil pump will limit how much you can raise the sump bowl, cant do to much about it the k series is a tall motor, just modify your bonnet its much easier.
