Anyone have any idea what kind of power the crank and rods from an LSX454 crate engine can handle?

Both are 4340 Forged Steel
Crank PN = 19170391
Rods PN = 19166964

Thanks for any help anyone can offer.

I want to drop the compression to about 8.5:1, change the cam to one of your turbo grinds, and then throw lots of boost at it with a single turbo, keeping the rpm limit to 6500....I just wanted to know the limits or if I should build a better one from scratch. Thanks.

that engine is really not going to be happy with boost.The pistons are too short to get a good ring land in +the bores are pretty big,this will lead to head gasket issues.
