Cam Problems

Agree Verne. Looks like Ken has a couple of items to check before looking at the cam manufacturer.

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.

Hi Steve:
Running a grooved cam in a 67 up block is no big deal really. We used to solder the rear cam bearing hole and redrill. Don't ask me the size, very small I remember. It is the bit in the top drawer of my tool box with tape on it LOL. The size is actually given in the how to hot rod BBC book.On the dist I am not sure. I never mixed them. My 66's were l-72's and I always used the 66 TI dist in them so had no issues. I did bake two cams like Ken however before I discovered I had the wrong rear cam bearing.Second one almost cost me the engine.
