| Extra HP & Torque I'm sure there is a thread about this already, if so can you please point me to the page or title. What I'm wondering is what can we do to our early 90's 4.9liters to give them some more HP. I haven't been able to find a performance chip, cold air intake or aftermarket exahust made for these models. Anyone know what I could do and where to get it.
Thanks |
