steel or cast crank for Stock Eliminator?

Putting together a GT/C '94 Camaro with a Jerico for IHRA Stock Eliminator ('71 LT1 350/330). Would you recommend running a cast crank? Solid lift cam should pull to 7,000 rpm. If not, should I just by-pass trying to find a GM steel piece and go aftermarket? If so anyone recommend a particular brand that they have had luck with or one that I should stay away from? I've heard the cast is lighter than the forged but was wondering if it would live behind a 4-speed.

Thanks for the help!

You have to use the crankshaft that came from the factory in that engine.

I would go cast, I know of many of SS cars that use cast and thier cranks last under must harsher conditions.

If IHRA Stock rules are like NHRA Stock rules, you must use a factory forging or casting. You can use a GM forged crank, that's what I'd run for the sake of longevity. A cast crank MIGHT be a little faster, but it'll be measured in hundredths, if at all.

I have been tempted, but the thought of taking the crank out in 3 easy pieces keeps me from going cast. Must be factory crank. Remember, your crankbone is connected to the transmission bone etc. with a stick!

Cast crankshaft, properly prepped is fine for that application... won't last any less than forged GM crank prepped the same. GM forged cranks aren't made of premo material and I have probably seen more cracked steel ones than cast...Make sure you select a core that has good cheeks on the top of the rod throws and good oil hole placement on the rod & main journals. Important to find a crank grinder that knows what he is doing as far a journal radius and to further enhance the life of your bearings, it helps emencely to have the crank surface hardened \ nitride or equivalent...

So Joe.. thanks for the vote of confidence.. just another post to get me to senior status like you are... unless Admin will just grant it...

With an automatic I would say it's a toss-up on the crank.

I would be leery of a cast crank in a high-horsepower stick car.
