351W Help
My truck has a 351W out of a 1978 Mustang in it now instead of the factory 302, which litterally melted down in 2000. I want to make the engine to High Performance, I need to know where I can find High Output Heads, Cams, Cranks, & Intake Manifolds. I know Jegs sells the stuff for a 302, but I'm not too sure about adding that stuff to a 351W. The truck right now has the factory 302 Intake manifold and injection system on it, but I am wondering, if I make it High Perforance, what all will I need to change, if any. Also I was wondering, can I put a 351W Fuel Injection system on it, with the 302 wiring harness and computer control module. Please let me know.

If your going to change all those parts, your also going to need better fuel injectors and a better exhaust to really get any advantage of the other parts. Yes you can use the 351 FI system (as long as your new intake is FI), but you'll need the 351 control module, not the 302's. Bigger throttle body is a must too.
Fairly sure summitracing.com has many of the parts your looking for.

No Mustang used a 351W engine after 1973 = none.
1974/78's are Mustang II's and only came with the 4 cylinder 2.3L, V6 2.8L and (1975/78) 302.

Sounds like your 351 is a 302.
Yuck! I drove one of those lame dog 78's with a 2.3L talk about a disapointment, cant believe they actually called it a mustang.

Any numbers on the block he can check to see which moter it is?
Not to go off topic, but... Ford should have made the 2.8L the base motor in those II's not stick some anemic 4 banger in it, it's a mustang after all! Dont know why but II's make me think of Charlies Angels.

Ford supplied all the cars for shows like Charlies Angels, Rockford Files, etc. Lorimar was the production company.
The dealer that supplied the cars for these TV shows was Walker-Buerge Ford, 11800 Santa Monica Blvd in West LA. It's just Buerge Ford today.
Charlies Angels: The office building where the cars were shown parked in front of, is on Little Santa Monica Blvd, south side of the street, 2 blocks west of Wilshire Blvd in Beverly Hills.
It's actually a medical building.

If the 351 has a taller deck height which results in a wider lifter valley than a 302, why would measuring the stroke be the only way to tell?

There are lots of aftermarket performance parts available for both motors, heads, cam, and intake will take you well beyond the capability if the stock EFI system however, so this will also have to be ugraded. You didn't say what year year truck is?

The only thing I know, is when my father purchased the motor back in 2000, when the POS 302 melted down, the guy he baught the 351W from, said it was out of a '78 Mustang. That does sound a little odd, because the only Mustangs with the V8, were the Boss 302's. I have owned 3, 302V8's, all of them, did not amount to a hill of anything. That is why we did away with them and stuck with the 351W. Now I have a question for you, if I wanted to put a 281, let's say out of a 60's model mustang in that truck, would it fit, especially with the EFI that's on it right now?

Let me ask you all this, if you had a 1989 Ford F150 Regular Cab, Long bed with a 302, espescially a low speed rear end, what would y'all do, in order to up the horsepower and torque to for one save fuel and still get about the same amount of power? I don't know very much at all, when it comes to fuel injections, I know carburators and stuff like that, but I'm not much into the Ford's past '84. I do know this much, that in 1985 is when Ford started putting fuel injection systems in all of their vehicles. Because I had a 1985 Mercury Cougar XR7 Turbo coupe, that had a 2.3L4 that had a fuel injection on it.

Headers and flowmaster or similar exhaust system, high flow cat. Same or better mpg, and better power. Bonus they sound sweet and you dont need to change anything with the stock FI. Down side, getting the old exhaust manifolds off if you do it yourself.

The next thing I'd suggest is to swap the heads on the '78 302 you have
for the late model E7TE heads found on nearly all SBF's after '87, this will bump compression slightly and improve airflow. Then you have to change the cam.. it's not helping, something like the CompCams 31-255-5 is a good upgrade and is EFI compatable. Combine all this with a decent exhaust system and the truck should return close to 20mpg at hwy cruise and mid teens city driving, and be a lot more fun to drive.
