I never said anything about it being superior to the 4g? I did say show me another N/A motor with high compression that can do 400whp on pump gas.
600whp on a 100% stock engine. How STOCK are we talking here? The last time i checked opening up the valve cover isnt stock. 272's are needed north of 450-500whp pending the turbo set up.Now if you are telling me people have made 600whp on e85/race gas with a STOCK bottom end. Then yes, i will beleive that.
But given the fact that arp head studs, MLS gasket and cams are needed above 500whp you might want to change your wording around. Stock is to easily thrown around here on cr.
