hello
i have a 92 crown victoria that i have been driving recently and have been thinking. would (or should) i build the 4.6L v8 in my car from 190hp to around 3-400? or buy a newer crown vic with a 5.0L v8 and build around the same amount? i need some input on this as a couple years down the road i want to finish a project for myself. i figured since the mustangs run the 5.0’s that they have more and better performance parts for them. i want to go from normal car to swift car if you know what i mean.
i am open to suggestions please. want to build it to possibly be used daily.
(btw my crown victoria has the F1AE engine in it).

but in your opinion which motor would serve me better? because i have a 4.6l v8 in my car right now and it can get the mileage and the reliability, just i dont know the 5.0L too well.
I have owned several versions of both, and I can tell you that you will spend a TON of money on a modular 4.6 and be dissapointed. Your EEC4 system would have limited compatibility — 4.6s need blowers, they have zero low end torque in a 4 cam. 2 cam isn’t even worth discussing.. 3o2s are cheap, parts everywhere, and there is just no comparison. Easier thing, just buy a car that suits your performance needs more. Better way to go if you want a big car with performance potential is find a full sized Gm with and Lt1 350 engines. Endless bolt on cheap potential there with none of the ford headaches, which, in my opinion simply not worth it.
what if i went ahead and bought a vic with a 302 in it, and mod that? im wondering if the 5.0’s in the interceptor vics are the same or a little different than the mustang. i would like to keep the car i have with the 4.6 because the 4.6 has plenty of torque for what i use it for, hence the fact that if i buy a interceptor with a 302 and build that. it is making a slow car fast but i want to make a sleeper, and see if i can get 600hp from the engine. lots of building required but it might still be cheaper than buying a new car lol.
600 Hp from a 4.6 two cam. Never gonna happen. And it would just expensive to a simple crazy amount. Even when Ford put a blower on a quad cam 4.6 motors they were dog dirt, completely. Recently I was looking at a corvette Z06 on a small car lot, and I happen to notice there was a later model cobra convertible next to it. Asked the saleman about it, and he said was simply a turd he had to gear down in the mountains. And that was a 4.6 with 4 cams a blower. 390 hp with zero torque I would guess. In about 1996 gm went a 3800 in an F body and made a joke about how their V6 base 3800 pony car would beat the Ford pony GT car with 4.6. And 3.8 Gm motors have much, more potential than 4.6 fords, plain and simple. A Grand Prix GTP with any mods at all will simply obliterate a 4.6 mustang, no race there. I have known some people who spent money on aftermarker blowers for 4.6 single cam motors (it on was a Saleen, but it should been called Saline, because as he might as well have put salt water in the engine and saved the headaches), and I have to say, they were no end of trouble. A 5.0 based motor has endless potential, but a 4.6 with 2 cams has none. Basically when Ford dropped the 5.0 engine in the early 90s, they had modular garbage for engines for years until this last new 5.0 came out, which is Ford trying to play upon their older more respected engines. It took them a couple decades to come up something competitive because their unfounded hatred of pushrods. I like older Fords, and have owned many of , but Ford has proven to be a bunch of idiots until very recently.
i get the fact that for horsepower the 4.6 is garbage, but would you think another vic with a 5.0 in it would be cool and able to do 600 hp.
A N/A 600 flywheel hp 5.0 liter can be done, but here what it takes. (incidently, I personally watched a splayed valve 400M ford make 780 on an engine dyno in my thin air, but ford M and C motors have better valve geometry and 2.19 or bigger intakes). Aftermarket block. Factory ones split right down the middle with less HP, even with a girdle. Aftermarket block with a forged 3.4 inch Crank, the factory is 3 inch – quite short, a set of really, really nasty heads, like a 2.08/1.60 valve aluminum heads (victor Jr, TrickFlow R, something like that) and a really aggressive solid roller cam. A carb, or carbs the size of Texas on an intake with no low speed driveabilty. 300 plus on the duration and huge lift. And about 12.5 compression. Has it been done, yes, about million times, daily driving, not a chance in the world. Whats wrong with a 350 hp engine thats manageable ? The motor I described above would have to be rebuilt about 2 weeks, where as a regular 302 with aluminum heads and even a flat tappet cam will run for years without issue.
It’s my understanding that you cannot buy a 5.0L V8 in a Crown Vic. Unless… you buy a LTD Crown Vic which is older and built on the Fox Body platform, which in my opinion are nicer. 4.6L Modulars are built to last not to perform hence why they’re equipped in Police Interceptors, Taxis, and various other applications. A Pushrod engine is MUCH better than a overhead cam, in my opinion. Much more simple in terms of parts, easier to modify, smaller package, cheaper, has a better seat in the pants feel when you mash the go pedal. You have other choices when you choose the Ford small block: 302, 5.0L from a fox body mustang, 351w from a larger truck, even crate engines. I have an SN95 Mustang that’s got the 3.8L pushrod engine that i’m swapping a pushrod v8 for. Torque feels better than revving high and not going anywhere. This is why Chevrolet uses LS series engines, they simply perform better. Whatever you choose is your choice. Be prepared though if you choose the Modular route, it gets pricey quick.
