411RWHP without polishing and porting the Plenum and Injectors Housings (a top notch job at that!) and without headers and an aftermarket tune is not possible on ALL MOTOR. Someone needs to check out their dyno! Those numbers are just plain wrong. Even with all of that...it isn't likely to be more than about ~410 RWHP at best. Gotta get into the heads to bring much more than 400 RWHP. A lot of guys here have done a lot of these mods and those numbers just don't add up. No way.
