ok i have a 90 gt with 3:73 gears, 155lph fuel pump, bbk cold air, flowmasters, smog pump removed, msd cap and rotor, msd coil, 9mm ford racing wires, and i have some underdrive pulleys on the way....now with them i wasnt going to put the alternator pulley on cause i didnt want to upgrade my alternator, but ive heard that pulley helps out alot??? is that true?? and my big question is what can i do next besides putting a new intake or heads?? im kinda on a budget for a while....i planned on bumping my timming to 14 and bypassing my ac with a shorter belt...but what else? ohh yeah someone told me to take the two black hoses that run into the throttle body spacer and hook them together, have you all ever heard of that??
