I am sorry to hear that it cam apart on you like that.I'd be frickin fumin and i imagine you are. A friend of mine from Vacaville has a Golden Eagle witht a new 304 that had a 8600 cam from summit that was cast improperly and roached the same way 6 moths after putting it in. Its been parked since March because of that too.
Summit gave him thefor the most part and actually until recently he thought maybe it was an oiling problem that casued the gears to strip like that. more recently he discovered the problem was more involved and could be blamed on poor manufacturing.
Good Luck

I've been hearing some rumblings on the AMC Forum also. It seems in a effort to minimize machining, some of the lobes are cast too small, and the lobe surface isn't fully machined. I've heard of some returns. Check the lobes closely.

If you need a tool and don't buy it...
you'll eventually pay for it...
and not have it.

lets just say summit has dropped out of the race for my cam choice.
It's the 8601....was it a 8600 or 8601?
What else then??? I've checked the IFSJ forums, and that's pretty much what they all run over there... They mention that the Edelbrock is too mild...
I am oging to run a 8600 in a 401 we have sitting here, if its bad the cam plug we are fabbing up withh keep it in check

Looking at my 8601 sitting here, some of the cam lobes are still in "cast" form....making them rougher than a cob. I do believe these are all supposed to have a "machined" finish, eh? I am not going to use a summit stick....I am looking other places now.
