I am trying out a new shop in my area called Ford Speed Racing. All parts being installed on my 2003 cobra are new: polished 2.3 whipple, accufab single blade T/B, EGR delete, 170 reische thermostat, gen II head cooling mod, 3.2 alternator pulley, PPRV delete, a new belt. I am very anal about my car as it only has 17,xxx miles so I will report back when the car is done to let you guys know how it goes. I forgot, they also have an in house dyno to tune my car after the install. I have a 4 pound lower and was gonna use stock 3.5 upper, hopefully I will see around 580 on a very conservative tune.
