Verne,
You may recall that there was a discussion on the NCRS site
some months ago about using early BBC ( rear journal grooved )
cams on later BBC combinations as long as the rear cam bearing
was modified to restrict oil flow to the rear of the cam.
I don't however recall anything mentioned about the distributor
issue that was mentioned here. Care to elaborate on that more?
I was considering this avenue for a planned L-88 build as
I have my eye on an early build L-88 cam. However, after
reading this post and many more like it, I'm petrified of
the down-side of cam failure. It seems that this is getting
out of control these days.
