How bad is a 20/20 crank?

[Buick Beginner]

Friends, Romans and Countrymen:
Lend me your ears! Actually your cranks! O.K. anyway I blew both head gaskets, (don't ask me how THAT happened), and pulled the motor for a rebuild. My crank is already a 20/20 crank but isn't damaged, nevertheless I decided to replace it. In my search for a better crank I've discovered that you need a brother with a bank to buy a standard, or even 10/10 crank. So my question is; How bad is a 20/20 crank? Can it handle 500 horses? I doubt I'll ever make that much anyway. Opinions? Thanks - BB

the .020/.020 is fine. we have had them in very stout units with no problems.

There's a guy down here running low 10's with a stock block 3500+lb GN that has a .020/.020 crank so you should be fine.....
