z400 vs. raptor stock for stock, if z cant beat it then what would it need to win?

 

a z with full pipe, and filter should come closer. Put in some cams and high comp piston and you should be beating raptors.

 

I went up against a Z400 this weekend at Glamis, the guy said he was just piped, filtered, you know the basic mods, well anyway, he smoked me, bad...I'm sure this guy had some other mods cuz I've never been beat by a Z...anyway, he smoked me 3 times a row, its all good though, I know he had some mods in there...
