Default stock crank

So I know the rods are the weak link in these motors, how strong are the pistons and crank?
Will they handle 500rwhp and 6500 rpm? Everything i've been reading says it shouldn't be an issue just making sure.

Btw, out of an Eaton, not nitrous. Thanks guys!!!!

I've never ran the stock crank with that power or RPM but I've also heard it shouldn't be an issue. The rods and pistons are the weak point.

You will definitely need a good set of pistons at that level.

I also have never ran a stock crank with that power or rpm, but read about guys doing it.

Never really understood why spending $5k+ on a motor and cheaping out on a $300 forged crank and you can spin it to the moon and throw as much boost as you want at it...but thats just me

If you want a reliable engine, and you have to ask the question, will this hold... don't do it.

just get the cobra crank man. I bought one for 150 off coral and spent 100 getting it inspected, turned, and polished. so 250 i've got a crank good enough for more than i'll ever need. I'll have about 1500 into my shortblock and it'll be rated for 900. hard to beat that.
