if youre going for cheap power, 4.2 shortblock with 99+ mustang intakes is the way to go. Putting stock single-port heads and intakes would be pointless, they just dont flow enough.
as for a stock shortblock with SSM heads/intakes/cam...I would guess around 230rwhp. Seriously though, if you got the same package for the splitport you could see 260-280rwhp.
