Alright i need some help here. I'm looking to some modifications on my 1997 F-150 Ext Cab, 4.2L V6, but im having problems on finding something to give it real power. what could i put on it. Where can i find it?
Yea, 375 is about right. The M90 has ALREADY been installed on a 4.2 F150. Stock engine. Results are as follows at 5psi non IC. 227.6 RWHP at approx. 5200 rpms, 290 ft/lb of TQ. A gain of about 10rwhp per lb of boost, pretty common.
