I have heard that the K-grind is about the same as the IPD 7001
or the Iskenderian VV71 (which are the same, I think, since the
last IPD 7001 cam I bought came in an Iskenderian box and
had paperwork with it identifying it as a VV71).
I don't know what the numbers are and I have not (yet)
put one in a B20E but on a B20E running carbs and on a B30A
the 7001 makes a BIG difference, especially over about 3000 rpm.
Idling is OK. Lugging torque is somewhat impaired at very low
speed but not badly. That means that if you don't keep your
car speed up, like turning a corner and then climbing a hill,
you need to downshift a little quicker, but when you do it
really takes off.
I would assume that the K cam would be pretty similar.
