Anyone have problems with .020/.020 cut?

[Black Demon]

May need an undercut after a wiped thrust bearing. (.010/.010 now)

Anyone have any problems?

Not really. I have seen some very fast cars with 30/30

I had a .010"/.030" going 11.78. Crank was never a problem..

Thanks for the replies. The rebuild budget looks better already!

I've heard of quite a few cars going 10's with .020/.020 cranks. Avoiding detonation is always the key .

10 on rods 20 on mains and a cut on thrust faces here Mike.
Give me a call. I am interested in what your crank is like when you get it out. I also have some bearing part # 's if you need them.
We need to figure out this thrust bearing thing. It's terrible!!!!

What main bearing do you all use on a 0.020" cut? Apparently the high performance bearings (Clevite MS960H or MS960V and Federal Mogul 107M) don't go beyond 0.010".

Clevite "P" series.

Thanks, Tim.

That's what I have sitting in my garage waiting for the crank to be turned. I was hoping that someone had a line on a high performance bearing for 0.020". Anybody ever use King MB-443-AM? It's supposed to be an aluminum-tin-copper alloy but I don't know how it stacks up against the Clevite MS960P.
