I recently bought a 1989 mustang
5.0 and the previous owner sent it to Steeda for upgrades. i would like if someone could explain to me what changes have been done and what effect they have on the car. Here are the list of upgrades that have been done.
1)Steeda H.O. Engine package
2)1 set friction (low) roller bearing rocker arms
3)Revised water pump and alternator pulley diameters
4)High flow air intake and filter
5)65mm throttle body
6)improved upper intake plenum
7)SVO 1-5/8" stainless steel headers
8)Fine tuned ECCU and ignition system
if someone could explain to me what 1, 2, 3, 5, 6, and 8 are and what effect they have.
