I have a SPF with a Roush 427R. Engine is stock except for an AED "Super Mod" carb that was custom built and dyno tuned for my motor. Suspension has Olthoff custom Bilsteins and Olthoff heavy sway bars. TKO 600 transmission. Torsen Type2, 3:27 rear. Avon CR6ZZ rubber.
Car runs 11:30s on a good day, 11:50s on an average day, 11:70s on a bad day. Top speed just under 125.
Not bad for a car that is geared and set up for road racing.
