![]() A high output in a 1986 Ford pickup truck?
![]() There's really not too much to be gained installing this in an '84 Mustang unless it runs absolutely perfectly, and with very low mileage. Granted you will most likely see more torque, but unless you plan on adding some parts to make it use all of its cubic inches, I'd save myself the trouble. It's not too difficult to install a 351 into a Fox body, but it will sit higher in the engine bay, which will necessitate a cowl hood or special engine mounts. Also, the added torque of a 351 (which is a real kick in the pants) will stress teh drivetrain considerably. Therefore you may have to upgrade the transmission and rear end. To summarize, yes it will work but with caveats. As to an actual horsepower measurement? Hmm....I believe it's probably around 170 for that year. Truck motors are made to make low-end torque, not so much in the horsepower department.

![]() Throw some half-decent heads on there with a matching cam & intake, invest in the drivetrain, and it may be worth it. I know if I had a transmission that wasn't blown (the AOD is shot in mine) and a running 351W, you bet I'd be stuffing it into the Mustang!
My crystal ball just got back from the shop. That's how I knew you didn't have the original engine in that truck. ![]()

![]() It depends on what kind of pistons were put in it. Are the flat tops, dish, or domes? If it was a stock-type rebuild, they are either dish or have the 4 eyebrows in them.

![]() Then, they could have as much as 10.0:1 compression. But it's probably more like 9.0-9.5:1. Do they not have the "eyebrows" in them?
