I saw a B20 K cam for sale in an IPD clearance many years ago
and asked about it at that time because the price was reasonable.
I think it was Scott who told me that while it had fairly good
duration that it was a smog cam and thus not quite the best for
performance. I have never been in a position to compare actual
specs between the K and the 7001 street perf cam. If any of you
have specs for the K I think I have the spec sheet that came
with my 7001 so maybe we can compare them.
I would guess that "K" is NOT an industry standard and am a little
surprised to find it is used on "modren" engines like the B21 and
following. (Actually I was impressed when the B18 was replaced
by the B20 and then the unbelievable B30, which at the time were
a great compromise between traditional ruggedness and pretty
good performance [able to beat Oldsmobiles in drag races].)
Next time you go to Joe Cox's Grinding Works in Tulsa or whatever
other shop you go to, maybe you should ask what they know about
the "K" grind. I am nearly caught up on cams these days so am
not frequenting those places. Haven't needed a crank ground since
about 1967. (S'pose I've been living right?)
