i would have to dissagree with the above..i would say get the inntake first folowed by mass air, then heads and then tb..we currently have a mustang running in the 12's with a 105 trap speed with only a e-cam and elderbrock heads..stock intake,tb and mass air..car also has 3.73 but no traction devises and not gutted..daily driver..
my reasoning behind this is that the heads and the cam are the "heart" of the motor IMO because they control the air being let in and out..the intake and tb air mearly air passages..i mean better flowing passages will help but they will work better with a stonger foundation a good base to build on..
