no one knows how fast it would be, but this car would probably be raped by one members stock pulley car.
3.8 pulley, headers and slicks = raped.
you need MANY MORE flow mods.
In otherwords you need headers or a PLOG and DP.
then consider an intercooler/cam/heads/rockers or three.
rockers and cam can be used together but they're not cost efficient.
Bottom line is the tune.
it alone will determine how fast the car is.
