Steel crank vs cast crank

Looks like I'm going to go with a 402 build on my big block.
I have a steel crank with crank-pins and main journals turned .010 under.
My question is... should I have the crank turned .020 under or should I go with a cast crank that is ready to go?
Any thoughts would be appreciated

Re: Steel crank vs cast crank

OK I've checked with many different sources, (Engine builder, Books, Race guys, and car nuts) The conclusion is the same

Engine builder said,
" Go with the steel crank"

Books say,
"Forged steel is much stronger the nodular cast iron, and is usually found in only racing engines. Big-block Chevys are an exception to this rule. Only the lowest horsepower versions use nodular-iron cranks. These engines are only the two-barrel 265HP 396, available only in 1969".

Race guys say,
"Steel crank!"

Car nuts say,
"Steel all the way"

So there it is. If there is anything else anyone can add, please do, I welcome your opinion
Thanks to all

Re: Steel crank vs cast crank

Mark your crank with your name and make sure they don't pull the ol' switcheroo on you!
