New Member, looking to get a SN95!

Asking the differences between a 4.6 and a 5.0 is a tricky question. Pushrod lovers as myself will tell you that the 4.6 is a pain to work on compared to the 5.0 and people who love the mod motors, 4.6 are so much better.

It’s like asking if white paint or black paint is better. It’s all a matter of opinion and preferences. You have to decide what you want and why you want it.

I would definitely find a lower mileage car, and half of your concerns are over. I've owned both the 5.0 and the 4.6. To be honest its your own preference really. I've had quite a few GT's over the years, and the only car I kept all these years is my 97 Gt. I wouldn't bother with looking fast until you actually are fast. I would spend my $ on a nice PI 4.6L engine and get rid of the NPI 4.6L, but keep the NPI for a rebuild later on for when you learn how to do that kinda stuff. A shifter will be fine, it will let you setup your shift knobs so your not bending shift forks in the transmission. The x pipe will be louder and make more horsepower in the higher rpm range. I would find a couple different cars and fully check them out, and don't narrow yourself down to one color and one style. The convertibles are the heaviest ones, so your already at a disadvantage. I would pick out around 5 different mustangs, with lower mileage, 5 speeds, and if you truly want a vert, pick out some of them. Make time with the owners to check them out, and if your not mechanically inclined I would take it to a shop somewhere and let a mechanic go over the car to see what you are looking at. A lot of Mustangs get rode hard and put up wet, so watch out for those. I hope this helps.

 

And remember the 99-04 are sn95's also, they are just called "new edge" sn95's.

 

Nobody will say that the 4.6 is anymore reliable. The 302, aka 5.0 is one of the most reliable motors ford ever made. That’s why it was so widely used for such a long time. It’s a tried and true work horse.

The 5.0 is a more simple platform that is more known for the torque it creates. The 4.6 is a little more complicated and a lil more expensive. The 4.6 does like higher rpms.

They both have their strengths and their weaknesses.

The 5.0 is much easier to learn on. Far fewer pets involved. The reasons people swap to 351w is strength of block, and the larger you can build it. 302 factory blocks won’t handle a whole lot over 500hp before the block has problems. The 351w has been pushed to well over 1,000hp depending on the year and usage. I have a 351w that’s going to the machine shop next month to be worked over as a 418w before it gets a turbo strapped to its big ass.

The 4.6 factory blocks can handle upwards of 500-600 hp if built correctly. But the cost can climb very fast.

I would stick to a 5.0 personally, cheaper and easier to work on. The 4.6 are good motors that will go forever if maintained well but without boost don't have much power potential. If a Cobra with a 4v is in your budget that would be a worthwhile alternative to the 5.0. It would also come with little upgrades like bigger brakes and such.

I've personally wanted to build a 408 SBF for awhile now.

 

Both engines are very capable. The older heaps known as pushrod are more versatile, ie carbureted or injected and will fit into just about anything. I remembered a company that made kits to fit a fuel injected 5.0l into a ford focus!!! Thats something a modular engine will not do!! And i personally know of folks that swapped in 5.0l coyotes after being true enthusiasts of pushrods for years only to remind themselves why the liked the pushrod engines....and then swap back to it!!!

But on a different note, the modulars are improved engineered for fuel milage and when forced induced become an extreme animal. Ill also state extracting power from one naturally aspirated is sort of a voodoo science. I really cant claim one platform having more torque than the other, but will mention the known modulars broader torque curve.

On a personal note. I curse and swear when im working on my swapped 5.4l 2valve, cause its HUGE!! But remind myself why i did the swap when i drive it.

 

5.0 looks better under the hood than a 4.6 even in stock form If that matters

 

Welcome to the site! You must live in a great area to daily a motorcycle for 4 years!

Both the 4.6 and 5.0 have a loyal following and have proven to be pretty reliable motors. I was a little intimidated when I first started working on my 4.6 but with some good advice here, I realized it's not all that bad.

When I searched for my car I didn't have a motor preference because I didn't know much about either. Price, v8, and manual were my only 3 criteria. If you stay open minded to either and just look for a deal on something that hits most of your requirements you can make enough power to have some fun

 

The best question to ask, is what do you want the car to do? A certain hp number? A certain 1/4 mile time? Staying N/a no matter what, or going centrifugal/roots/turbo? Corner Carver?

Most people's problems are created by people just throwing parts at a car and then being disappointed or unsatisfied with the results. Decide what you want, then as each piece gets added youre always marching in a straight line to your goal.
Some things are better on a 5.0. Aftermarket aluminum heads, the big bore, and cheap cams make NA power easier to get by far.
If you're keeping it fairly stock, I like the 4.6. At 100-150k change the timing chain guides (unless you're in there modding anyway), keep it full of oil and coolant and they run damn near forever. I don't find them hard to work on, though cams are definitely more expensive.

 

Op where are you in Florida? Ive been thinking about letting my 02 gt go though its a coupe.

 

Its not 100% stock no. Its the one in my signature if you are on the desktop website. Its been sitting on the back burner for a while but right now I just dont have the time. Pm me if you want more info.

 

I realize you are all the way across the country but I would look for something like this... https://albuquerque.craigslist.org/cto/d/albuquerque-1997-ford-mustang-cobra/6799052431.html
