Mopar drag engineers, Tom Hoover and others, did a lot of A,B,A tesing on many different valve bodies, shift kits and so on back in the late 1960 and early 1970s. T/A manual valve bodies at that time where measurably better than the rest out there back then I heard later that Winters came up with one that might have been .002 to .003 better than the T/A, maybe not due to weather and track changes in the time it takes to change the V.B. All of the LBA I've heard of are a little slower than the same brand no L.B.A. valve bodies More reasons to have a very good front drum instead of a stocker
