It differs so much on the tune and other parts, fuel system, intake, heads, exhaust, etc... That's why the post numbers for stock motors... and prolly not with a 'safe tune'...
It IS deadly! Very much so! My new thinking is that +400 RWHP you NEED a build shortblock, hence count $10,000 for a cooled SC install, inkluding a shortblock and upgraded fuel system for safe running!
I wonder if Saleen, Roush, FR, etc. are going to run into probs with warranty issues... it's gonna be pricey to start rebuilding motors... on the other hand they are plaing it safe with low boost and safe tunes... and if you change that...guess what...!!
Our internals are a joke! cheapest/thinnest alloys they could find it seams...!!
