How much HP are Scat 4340 Forged I-Beam rods good to?

GOt some people giving me **** about these rods that I got saying they'll put a nice hole in my pan. I think they'll be fine if I hit around 450ish flywheel....

Thoughts, experiences, and opinions?

Thanks!

MORE IMPORTANTLY,
how many rpms are they good for

cranks seem to take a lot of abuse hp wise but rpms kill them

Tell these people you'll be happy to run whatever rods they buy for you

I have no personal experience with the parts in question but do a search for anything posted by Mindgame. I believe he said he ran some Scat I-beams pretty hard in a circle track engine and they held up fine.

You're not going to get a cut and dry answer as there are too many variables to take into account. But provided you're not using granite slugs for pistons I think they'll be fine at 450hp and <7000rpm

Stop listening to people, 99% of the time (especially on those big automotive message boards online... ;) ) they don't know their *** from a hole in the ground. You've got more connecting rod than most people ever need, and it's doubtful you'll have issues.

I know 5.7, but what measurement is the 2.0/2.1".

And do I want bushed or press pin?
