I had a long talk with WL at Earlvile last year he wanted to check this at indy but was told no So until they start checking stockers it is a gray area. Yes there are a bunch of it out there. Tom

I believe there's some very fast cars running them in stock. Bob

Al,
You said it all...

The advantages of the 50mm cams are 1) larger base circle so the profile can have more detail, 2) cam companies have some body of experience/knowledge with these dimensions since Pro Stock and NASCAR have been doing this for decades, 3) roller bearings are readily available for this size. There are also some 65 mm cams running around in American auto racing arenas for very specialty applications.

I will tell you about the ring pack because i dont really care anymore.
The less you spend on the rings the faster you will go.
The key is the clearances and the surface prep, how about that.

Wow, I can't think of but 2 instances that apply here -

1. You don't build any engines that compete in a competitive racing series.

or

2. You know someone who does, and they are lying to you.

Jim
I'm not shy, here's my opinion for what its worth.....
No the 50mm, 55, 65...what ever should NOT be legal in stock!!!
It would be nice to add competitors to our class, not drive them away, the added cost to me would far outway the performance gains....
