Cam warning-Please read!

[Dave Walters <whdavid@xxxxxxxxx>]

If anyone has bought a Racer Brown B/RB cam recently,I want to offer 
some important advice.I bought an STX-20 around Christmas and eventually 
installed it about 4 weeks ago.The cam had core shift issues which 
placed the lobes too far to the rear of the block.In short,a lobe would 
hit the lifter next to it as the engine rotated.Also,1/3 of the lifter 
hung over the side of the nose of the lobe,so it wasn't a matter of just 
narrowing the lobe a bit.

I caught this during assembly,so no damage was done.I sent Jim 
Dowell(Racer Brown) pics of everything,and he said he hasn't received 
any other complaints.Cams could be on customer shelves waiting to be 
used.

If you do your own assembly please be aware of this issue as a matter of 
habit.Some guys check for these issues,some don't.I'd hate to see 
anybody's new motor get wiped out.If you have the work farmed out, 
please make your machinest aware of the potential problem.There has to 
be more than one bad core out there.
