Swapping out a Voodoo

Remember that MOST HR profiles are for a SBC sized Base Circle and small wheel
not a MOPAR /BBC size base circle and none that I know of have a MOPAR big wheel in the lifter (an edge you can get with a solid roller- less side thrust)
so- check with your grinder
no mis/match problem with a SBC sized base circle which will drop the lifter down (hopefully) into the no problem zone
one reason why regrinds can work - but check the hardness depth
