So im learning about the 4.6 as i go here. Installed the throttle body and intake and dropped 3 tenths off the 1/4 mile e.t. It now runs a 13.9 @ 101 mph. I was thinking of going with the short shifter and bigger mass air meter next. Does this sound logical or should i do something else first. Already have h pipe, cat back exh, 3.73 gears, underdrive pulleys, and cold air intake.

 

Thanks-Keith
