[Fot] cam followers (lifters)

[Jack W. Drews]

I just thought I'd pass on a little info on lifters that might be of 
use to somebody.

To the best of my knowledge, lifters for the TR3-4 are sold by 
British Frame and Engine, Moss, TRF, and British Parts Northwest.

I tested 30 or 40 lifters from various sources. Of the lifters I've 
tested, I find that BPNW lifters do have a hardness between 54 and 60 
Rockwell C. In addition, if you have the lifters refaced by Riddle 
Machine in Santa Ana CA, the hardness after refacing averages 57 Rockwell C.
