I hope so. I've gott hem in my truck's 360...lol. There was a trend to go with full groove bearings. Personally I've never "bit" on that one for a street/strip or strip engine. I have run 3/4 groove in some applications but IMO you don't need full groove unless you're really revving it or sustaining high rpms - like in road racing. It is much more critical to have the bearing bores machined well, and the wear surface machined well. King has tighter quality control and the result is a better product IMO. That doesn't mean FM is crap, it's not. But it isn't the top of the line. IMO - King is. However, if the machining isn't high quality too, then the top of the line bearing isn't going to be at it's best either.
