Here we go with another Falters theory time again Kids! Mr. Hardtimes, I have forgotten to ask if your lifters and cam were new, or reground??? If it was as Falters theory goes, I should have gotten all the motors with B cams, and Model A lifters back. Gosh, How could I be so Lucky. If you are using shorter Model A lifters, that would make no difference at all with adjustable Lifters. I just have checked the New lifters in Dave's engine, from Ne. and the new lifters that had a Model B parts number on them, stick past the fresh ground "A" lobe anywhere from .040 to .055 thousandths, each side of the Model A lobe, plenty to handle the Model B cam. Now if you want the "A" lifters, If you cant find any B's to match the cam lobe surface, you can releave the lobe on the cam .035 on each, if for some reanson you want them to match, but I wouldn't. I have never seen a Model T cam that didn't have a portion of the toe, at standard length, and the rest of the toe that was wore .020, or less. Herm.

P.S. The lifters came from Berts Model A, and they are a hard body, as the lifter body, and bolt will laugh at a file! I am sure other places have them as well.
