Default 427 turbos

I am wanting to see what size trbos are you guys runnings on 427 twin setup?
I am in the process of gathering parts for my build. I want to be between 750-900rwhp, but I don't plan on running high levels of boost. thanks

Anyone of the 60mm turbos will get you where you want. I would contact Jose from forcedinductions.com He is good at sizing turbos...

I'd think you'd be looking at 66/67mm twins to hit those kinds of numbers. Twin 60mm turbos should make 900rwhp but I'd research if they can handle the airflow of the stroker.

A 427 would choke on those small comp. covers!!!! You definately need something along the line of a 66mm,with a good a/r and nice exhaust housing with that big of a motor!!!!

You're nuts if you buy eBay turbos, seems very risky. Try some of the sponsors in here for quotes.
