I have the 1200 FITech, but all the throttle bodies only flow ~830cfm, so take that into consideration. The ET was very close to my 950hp Holley, fuel mileage took a lot of work to get to where I was with a 750 vac sec carb. A lot of tuning decel fuel cut, leaning out part throttle cruise, etc

Faster, Faster until the thrill of speed overcomes the fear of death...

71 Swinger - slowly collecting dust/parts
66 Belv. II - just a streetcar
88 Mustang - turbo LS beater
