I don't think you need the whole harness but I could be wrong i'm not a mustang guy. start off with just the intake and throttle body parts, as well as swapping the computer. if it turns out that additional wiring for the MAS is required then your can start into the harness.

other than those parts, the two motors are exactly the same. just make sure to replace any gaskets on the intake manifold and torque the bolts properly to ensure a good seal. other than that it should be an easy job.

Mustang motors and truck motors have different size cams and valves, yes the blocks are identical but the internals aren't. So be careful on a swap like that it's always best to use the motor the parts come off of.

I have a 1993 F-150 Flareside that gets horrible gas mileage. I have put shorty headers on, K&N intake, flowmaster, and an MSD ignition coil. I didn't think that these add ons would effect my mileage this much. I hardly ever reve it over 2500 and drive it fairly respectfully. I am currently getting 10 mpg. I have the suspision that something might wrong either in the motor or somewhare else. Can anyone give me some clues as to what might be arong with my truck or is the price i have to pay for power. Also can anyone give me a horsepower estimate for a 5.0 with these Add ons? Thanks.

I WOULD ALSO CHECK THE IGNAL TIMEING IT MIGHT BE AT 8DEGREES YOU CAN ADVANCE IT TO 12 DEGREES AND STILL BE SMOG LEGAL BUT IF IT PINGS YOU HAVE TO PUT IT BACK (POST )

I know of a product that is more effective than a truck bed cover, or a cap.

its a device I manufacture that improves air flow near the tailgate, that doesn't weigh more than 10lbs, and has been tested and proven to increase fuel mileage by as much as 5 mpg.

this product can also be easily removed for full use of your truck bed. by getting better mileage with your tailgate on, it also prevents undue stress and cracking in older trucks.

I run this product on all of my families trucks, and company trucks.

per truck it saves $400 to $600 per year.


if you would like to know more please email me at dankraft@live.ca

I have photos and test results available


So if i remove my cap and install your product my mpg will increase.
and what is the price for said item??
