What parts can you upgrade on a Ford 351?
351 Windsor blocks upgrade easily. A huge number of aftermarket parts exist for both the 351 and the 302. Popular upgrades are the heads, since the stock 351 heads are mediocre at best, and other standard upgrade parts like the intake, cam, headers, and fuel delivery system.
What is a Ford 351 Windsor engine?
What is a 351 Windsor Exactly? The 351 Windsor (351w for short) is the largest of the Ford Small Block engine family. Ford Motor Company built them between 1969 and 1996.
How can I increase the power of my 351W engine?
In most cases you will see top end power increases through performance camshafts on most engines. Significant gains on the 351W can be made from cam upgrades. Altering the cam profile alters the intake and exhaust durations on the engine and can dramatically change the bhp and power output.
Will a 302 head fit on a 351 engine?
It should be noted that the 351 has larger head bolt holes than the 302. This means the same heads will fit, but a 302 head will need to be drilled out to accommodate this if it’s being used on a 351. A popular example of this is the GT40 head used on higher performance 302 engines being swapped into a 351 for higher flow numbers.
How much HP does a stock 351 Windsor have?
While the latest generation of 351 Windsors typically generated around 180-220 horsepower from the factory, adding a new set of heads, a larger cam, and some other aftermarket parts can get a Windsor with the stock stroke to around 350-400 horsepower easily.
What can a 351W be stroked to?
The 351W gets stroked a half-inch by fitting the block with a 400M crankshaft (the 400M is a tall-deck Cleveland). Keep in mind the 351W has a 3.50-inch stroke while the 400M has 4 inches of stroke.

How many cubic inches can you get out of a 351 Windsor?
Various levels of compression make these kits great for all types of setups. This stroker combination uses a 3.850" stroke to produce 393 cubic inches from a 351 Windsor engine.
How much horsepower can you get out of a 302 motor?
Standard Ford 289 and 302 small-blocks were factory-rated between 200 and 230 hp. The vaunted 289 High-Performance engine was said to make 271 hp. Today, if a 302 Ford makes 360 hp on pump gas with a hydraulic cam, most experts consider it to be a pretty good motor-at least until Joe Sherman steps up to the plate.
When did Ford introduce the 302 engine?
The 302 first appeared in 1968 as the successor to the 289 small block V8. The list of cars the 302 came in is virtually endless. Perhaps the most widely known use of the 302 V8 is its use in Ford Mustangs and Mercury Cougars.
What is a 408 stroker?
Our 408 Stroker Crate Engine is built with a 350 block and a 4-inch stroker crank. That's right! A 350 Chevy with the same block clearance as a 383 and a standard base circle cam houses a big block stroke and 6-inch rod. The torque in this thing will give you goosebumps!
What's the difference between a 351 Cleveland and a 351 Windsor?
Cleveland/Modified engines have the timing chain recessed into the front of the block itself, and its timing cover is essentially just a flat piece of metal. The Windsor's timing chain attaches to the front of the engine and has an external timing cover typically made of cast aluminum.

What parts do I need for a 351 short block?
Other 351-specific parts you will need are an intake manifold, distributor, and exhaust headers. A stock truck EFI distributor will get the job done if you can find one, otherwise you'll have to look to the aftermarket.
What intake manifolds are used on a 351 Windsor?
With the heads and camshaft chosen, we're looking at two options in particular for our 351 Windsor build-the Trick Flow R-series intake manifold, and the Edelbrock Victor 5.8 intake manifold. The Trick Flow R-series for the 351 features 13.3-inch-long runners, a 2.00x1.20 port size at the head, and an 11.5-inch overall height. With a 75mm throttle body, Trick Flow claims the R-series will support a rev range of 1,500 to 5,500, but stepping the throttle body up to a 90mm piece will broaden the rev range to 2,000 rpm to 7,000 rpm.
How much does the LS6 lift the valves?
Whereas the LS6 lifted the valves 0.550 inches, we'll be limited to about 0.500. One could make this up with the duration and lobe separation angle, but we intend to keep a stock idle and driveability characteristics, similar to the LS engines. If you want to add the hot cam and deal with the reduced driveability, then have at it, but a smooth idle and stock driveability are high priorities for this buildup, and the increased displacement should offer plenty of power and torque for us to have fun with on our daily commute.
What is the rev range of a 351 Windsor?
We're also considering Trick Flow's Box R-series intake manifolds for Ford 351 Windsor, which cuts the runner length to 11 inches to support a rev range of 2,500 to 7,500 pm. Though our 351 is substantially larger than the 302 it will replace, it's probably not enough cubes to keep the air moving efficiently through the box design. We may test it down the road just to illustrate how it works in this rather mild application.
How much are Comp Cam rockers?
We'll be using Comp Cam's latest rocker arms, these Ultra-Gold aluminum rockers ($254.75 retail), in a 1.6:1 ratio. They're stud-mounted pieces that are built tough to withstand high spring pressures, while offering plenty of clearance to accommodate such larger springs.
How many horsepower does a 5.8 liter EFI have?
The Edelbrock Victor Ford 5.8L EFI intake is designed to work from 4,000 to 7,500 rpm, and is capable of supporting over 700 hp. The Victor Ford 5.8L features Edelbrock's air-gap design, which isolates the intake charge from the engine heat that is present in the lifter valley.
Can you live with stock 5.0L power?
But common sense strikes and you also realize that you cannot live with stock 5.0L power. What does one do in this predicament? Build a 351 Windsor engine.
How much horsepower does a 357ci Windsor have?
Building on the foundation of our previous build, meet Dirty Harry, the 357ci Windsor that pummeled our eardrums with its 7,500-rpm redline and a whopping 595 hp.
What kind of bearings do Fred and Brian use?
Fred and Brian assembled the engine with Clevite H-series bearings and ARP fasteners . The connecting-rod bearings are narrow to fit the crankshaft's radiused journals. Note the "lower" designation stamped on the back of the bearing. Be sure to check for this. If bearings are installed in the wrong orientation, they can contact the crank fillet and cause all kinds of problems.
What oil pump did Fred use?
Fred completed assembly of the bottom end with the installation of a Melling Select high-volume oil pump and a Moroso pick-up tube and pan. We replaced the spindly stock oil-pump drive with a much stronger one from ARP. This combination of parts provided 58-psi oil pressure at idle and a solid 7076 psi throughout the dyno pulls.
What did Brian surface on the pistons?
In addition to the overbore and hone, Brian surfaced the block to zero-deck the pistons. He also opened up the oil passage from the oil pump to the filter and cleaned up the radius between the two, as shown by the wire inserted through the oil-filter feed.
Can you run a 3,000 pound engine on race gas?
It runs happily on a pump gas/race gas mix, or get an E85 carburetor and run it solely on "pump gas" if it's available. The best thing is that this engine is built to take some abuse with a power-adder, so throw some nitrous or boost at it with dedicated race gas, and your car will be a contender.
History of the 351W Engine
In the 1990s, the 5.8 L, 351W was switched from speed density to MAF, which resulted in performance increases.
Best 351W mods
The best 351W parts on an engine are in our opinion the ones that give the best power gain for you spend.
Best Engine Mods for your 351W
Mapping - remapping provides the biggest gains for the money, aftermarket ECUs, and piggyback ECUs are all alternatives.
351W Tuning Stages
Typical stage 1 mods often include: Sports exhaust manifold, Intake headers, Panel air filters, Fast road camshaft, Remaps/piggy back ECU, Drilled & smoothed airbox.
351W Camshaft Upgrades
Fast road cams work better at top end power and we generally recommend this as a primary mod on petrol engines, and secondary on Diesels to a remap. In most cases you will see top end power increases through performance camshafts on most engines.
ECU Mapping Improvements for the 351W
A remap helps unlock the full potential of all the parts you've fitted to your 351W.
Air Flow improvements on the 351W
It is the whole point to any engine upgrade job to feed more fuel and air into each cylinder
What is a 351 long rod?
What you are referring to with the longer rods (assuming you are still talking about the 351w), is known as a 351 long rod. It uses a 6.125" rod with the stock 3.5" stroke and a ~1.6 compression height piston to achieve a better rod ratio. This provides more dwell at the top of the stroke which, in theory, will make more power. In reality the amount of torque gained is minuscule, I think its about 2%. Don't waste your money.
What rods are used for a cheap stroker kit?
I'm going off my memory here, but the 'cheap' stroker kit you speak of is done by running a 400M crank, Chrysler 360 rods, although I don't recall which pistons are used.
How to offset grind a Chrysler crank?
You have to turn the end of the crank down so the timing set sits flush, and turn the rod journals down to 2.124" to fit the Chrysler rods. When you do this you can also offset grind it by as much as .125" which with a .060 overbore nets 427cu. in. You can offset grind it less, and get less displacement and compression.
Can you go straight for a 351W?
So, if you want brute low end torque windsor, ditch the 5.0 altogether and go straight for a 351w. If you can afford it stroke it out to 393, 408, or even 427. If you can't afford to go that big you can still get decent numbers on a stock 351" motor.
Can I use a 400m crank with stock rods?
im sure there is many rotating assembly combinations that can be used for multiple specs but i am almost positive a 400m crank with stock rods and 302 pistons can be used. As for the modification to the crank you mentioned i would not be surprised as no customizing goes smoothly but like i said i have heard of this never experienced or known anyone that has tried it. Personally i would not consider these "budget" builds as the cost of having it properly built is fairly decent now days.
How much horsepower does a 302 have?
The easiest way to demonstrate this is if you had a 302 with heads that made a peak of 450hp at 6500 RPM and used these same heads on a 419ci Windsor it would probably still only make around 450 peak hp, but at a paltry 5000 RPM’s. Simply put, make sure you increase the port volume and airflow capability to match your new displacement so you aren’t disappointed.
What is piston in a kit?
Pistons are the last major component in the kit . They have an exact pin height for the additional stroke and matched connecting rod. Kits include pistons that will not only ensure that you don’t have deck clearance problems, but also fit the rod correctly and clear the crankshaft during rotation. They will allow for correct compression ratio with the longer stroke.
What is a stroker crank?
The stroker cranks are a little more complex than just having additional stroke. The counterweights and journals of strokers are set up for specific connecting rod dimensions: journal sizes and lengths. A kit matches the rods with the exact crank, so you don’t have to worry about your pistons hitting the rods or if the rods bolt onto the crank correctly.
How to keep a huge displacement stroker happy?
An increased plenum size and more efficient intake manifold and carb or throttle body are a few places to start. Air cleaner choices and removal of air restrictions of any kind will keep your huge displacement stroker happy all the way down the track.
What is the base of a stroker monster?
The base of any good stroker monster combo is the engine block and there are many options to choose from. Blocks are available in a wide variety of configurations, so make sure you choose the correct block for your application.
Why do you need to limit the stroke on a turbo?
Also, as the stroke increases, the piston wrist pin moves higher and higher inside the piston to compensate and piston skirts become shorter.
Is a piston made of aluminum?
Notice the cap screw bolts on the H-Beam rods instead of the bolt and nut combination. Yes, all pistons are aluminum. It is how they are manufactured that makes the difference in strength, as well as material. Hypereutectic pistons are formed by a process that distributes silicon equally throughout the alloy.
