TR2, TR3, TR4, TR4A, TR5, & TR6 PROFILES
We recommend having these cams nitrided after grinding because of
the wear problems they are known for.
We especially recommend it for the early engines without cam
bearings. The valve lifters
are made from soft chilled iron and almost always go bad so it would be
best if you sent them along with your cam so we could measure the radius
crown height and regrind them.
DIAM. TR2, 3, 4 = .936
TR6 = .800
ROCKER RATIO = 1.45:1
