Pauter?
Crower?
Eagle?

I'm only aiming for 420hp can I just use stock, maybe send them out to be cryo'd

oh and while you are here, tell me what pistons you would suggest and why.

Pauter for that extra Piece of mind

Sub-Zero

Running 427 rwhp with Sub Zero Cryoed rods. No problem. Cheapest route. If you want a little better go Eagle for less than $400. If you want more go Crower lite for over $600. Finally if you want more, but you don't need it, go Pauter.

I would just go with Cryoed rods for 420

but you know you want to get the Pauter so just do it!

moonliver

you are thinking hydro

What do people mean by Cryoed rods? I can not find much info. Is it a brand or a type of treatment for the metal?

I don't know why this motor is even being discussed for opening up for 420whp, such a waste of money and time and actually risk problems. There is nothing more reliable then an un cracked F20/F22 unless you are really pushing the envelope of the components, which you are far from. People run these engines all day on E85 600whp+. 420whp is like a standard 10/12psi stage 2 kit of your fav option. DD that on a bone stock engine reliably for years. Stock rods are not the lightest but they are very strong.

Yup.

What does that have to do with the rod strength?
