Default Re: Model B adjustable Lifters ?

Its been awhile since I have bought lifters, but a set of the so called double nut lock lifters I had were about .995 in diameter. Stock specs called for a lifter base of 1.110-1.125 for the A. I have not seen B specs but understand they are the same. One set of the " single" lock I bought were 1.17 and worked fine on a modified A cam and I think is the one shown in Vince's picture. Had another set once that was 1.110. I guess the lesson is to measure them before you buy or use them. The cam grinder guys Brierely and Stipe will know a lot more about what can be used. YOu can check it out when you assemble the engine. Use Prussian Blue on the lifter base and the cam lobe wiping mark should be entirely within the base diameter.
