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?)
