What exactly are the advantages of getting a 5.0L? People always talk about them so whats the deal? Why should I get one of those over lets say a 302? Like do they come with power steering since they're newer? And if they're worth it, will it fit in my car? (1966 200 ci)

A 5.0 is a 502. 5 liters is 302 cubic inches. 5.0 is referred to as the 302 offered since early 80's but is still a 302. A newer 5.0 is a roller motor. Roller cam motor that is. You can easily convert and older 302 to a roller. They also have fuel injection and serpentine belts. If your looking to put one in your 66, you need deep pockets. You not only need the motor and fuel injection, but the computer as well. Yes a 302 will fit in your car.
 
The only 5.0 motor that has a real advantage over an older 302 are the roller cam motors. A roller allows a cam profile that out performs a flat-tappet design of the same lift/duration. The roller lifters also reduce friction. The late model E7TE heads also breathe a little better than the older heads. The crankshafts in post 82 motors also weigh less than their older counterparts ( less rotating mass = more power) Other than these differences, there's not much different between the older and newer motors aside from EFI
 
5.0's are metric, which as we all know is superior to a 302 since the metric system is better than the american standard.... that being said, modifying an inline-6 to a V8 at all is a lot of work, from what i've read on this forum. the 5.0/302 motor is almost idendical to a 289 on the outside, so can drop right into a 289-based car. the 302 is a great motor for stroking, as well.

depending on who you ask and how much $$$ you have, some people would tell you to start with a V8 car for mods rather than trying to convert an I-6. i have no experience with that, however. i've seen some pretty wicked I-6's on here, though.

:rlaugh: :rlaugh: That's a joke, right.

302 Cubic inches equals 4.94889 Liters

They are technically EQUAL

Just different ways of measuring the same thing
 
I am doing the 5.0 swap using a hopped up 91 GT motor and AOD into a '68. (hopped up motor meaning GT-40Y heads, e-303 cam, 65mm Throttle body, GT-40 intake, and some other minor mods. :nice: ) The car origianlly had a 302 and C4, just pulled it- want to buy it? (sorry cheap plug :shrug: ) The total swap will cost me about $2400. (not including the new engine parts) It has got to cost about twice that amount to beef up the suspension on the 6cyl and what ever else you have to do. Just wanted to give a cost idea.

I converted my I-6 65 convert to 5.0. Yes, it was/is a lot of work (almost finished), but a major upgrade in the car's performance. The 5.0 is the same block as the 289, so everything fits - the T-5 transmission shifter even comes up through the floor in the same place!!! (Use 66 motor mounts) The computer and wiring can be a bit pricy (the conversion engine wiring harness alone was almost $500 from Ford), but I bought the engine, trans, computer and original harness in a package from one donor car and that helped. Be sure to get all the sensors with the engine, especially the barometric pressure sensor.

Replacing the entire suspension front and rear takes a bit, but is necessary if you're starting with a 6 (I upgraded plus dropped it one inch all around) if you're gonna handle the extra power. Stronger rearend and 4-wheel power disc brakes are worth the effort. Price? I have less than $1000 in the suspension changeover. Not counting the Torque Thrust Ds and Michelins, of course :o) they were a bit more than that! You can triple that if you go to rack & pinion Mustang II front (kits are available to change over) but that would only be necessary for a serious competition road car.

It is a lot of work but worth it, I think. Just depends on what you want in a car. Mustangs Plus in California has a lot of the pieces you need and some good instructions on particulars.

:rlaugh: :lol: :rlaugh: ,,,,,, Please tell me you were only kidding?? There's nothing metric about the 5.0 other than the liter designation. All the bolts in them have SAE standard threads. :doh:
 
I was recently quoted 750 plus tax for a EFI conversion, including everything brand new or refurbished, upper and lower intake, complete wiring harness, etc... But the manifolds are stock specs and same with everything else. Good starting point I think. Anyone get a good junkyard price??

Ps my 5.7 is better than all of yours :lol:
 
And to answer your original questions brtnstrns the EFI 5.0 is more reliable and I beleive you can plug alot more power with the roller motors. The engine probably will have power steering, but Im not sure if you can use the same system on a classic. And yes they will fit in your car, its exactly the same size of your 302/289 only with fuel injection.

The 5.0 HO's (the ones with the roller cams) are well built for all the previously stated reasons, but nobody mentioned the fact that they had forged pistons, most engines have cast pistons. (or those icky hypereutectic ones but we wont go there)

Do you have a wiring diagram for the installation...I could use one. :p
