Foxbody Mustang respond very well to certain bolt ons. 1.72 roller rockers not only add lift but also have less friction than the OEM rockers. I got these used off CL…wow are these hefty. I had to purchase Canton valve covers from Summit Racing, to clear the rockers. They still tapped the oil baffle in the Cantons, so I had to grind it down a bit. To be exact, 1.72 rr increase the stock cam’s lift of .444 to .472.
I found a Ron Davis 3-row aluminum radiator on CL cheap. I noticed my fan had tiny spider cracks in the corners…a common problem on foxes. From PPI, I found a new Ford OEM fan and a Ford Police spec fan clutch with a Cobra R overdrive water pump pulley. The police clutch runs faster at lower rpms and less at higher, freeing up some hps and the pulley provides greater fluid flow.
I really like the Ford Explorer intake…an early version of the GT-40. It performs really well and has a stock look. I found a Explorer intake and Gen3 EV1 injectors from Mustang Mike in Arizona. The Gen3 EV1 injectors provide a better, more efficient spray pattern than my older 1991 injectors. They have a 3-point spray pattern, opposed to a single. I found 65mm EGR + throttle body on CL and everything gets routed to a BBK cold air intake that came on the car, with an older generation chrome Pro-M Bullitt mass air meter I bought on eBay from Dugan Racing.
Here’s a help comparison chart from Super Ford Magazine in 2000
Ricky at American muffler installs my 2 1/2″ exhaust system. FRPP shorty headers off CL, a Summit X-Pipe which is dirt cheap, and Magnaflow mufflers I found on CL, all exiting out a set of LX SS tail pipes I got at LRS. The tail pipes were a tuff job, they have to be routed through the Maximum Motorsport’s pan hard brace and fit through the Saleen rear valence skirt….what a PITA!
