This car came from Roush 'stock' with thier top end on a factory 4.6L short block - including the Eaton M112 supercharger @ 6 psi.I consider anything NON-stock as with anything that has changed the performance of an engine.
The built aluminum short block I swapped in is all Ford goodies as well - just not an option for them back in '98. Shaved something like 70 lbs off the nose weight of the car.
Car also has Ford Racing aluminum flywheel, Ford Racing OEM clutch, Cobra spec T56 (w/ Roush shifter), Ford Racing aluminum drive shaft and Ford Racing 3.55 gears. Full suspension/brake upgrades are all "stock" Roush. The wheels are Roush 18x9/10 off my 2000 (now sold). I have stock 18" from this car just in case I sell and the buyer wants it original. It has the Roush leather interior, pedals, gauge cluster, dash trim, trunk mounted tool kit etc...
The non-stock upgrades are somewhat limited: Steeda trunk mount battery, Steeda firewall adjustable clutch cable and triple pick up aluminum quad, Autometer boost/vac gauge and in dash DVD. I have two trunk lids. Street use gets the Steeda race wing (as pictured). The other is a track oriented adjustable plane wing that I use solely for events. Not really a street friendly wing. Haha.
