Ok... I am looking at an I think 1976 Mercury Comet... Though it has no engine in it. It does have a C4 Tranny and Im the type that wants a 5-speed... Since it doesn't have an Engine, and Im wanting a 5spd... Would it be better to try and get an Engine from a mid 80s with the desired tranny attached, rather then getting an engine from the cars year then trying to get the tranny to fit... Would an 80s 302 engine and trans fit without much trouble? Thanks!
All the 302's are the same size. However if you can find a block and tranny already attached, I would think this would eliminate the need to find the parts that fit.
Yep, bunches of us have done it both ways. I now have a 5.0 motor with a T5 but I originally ran the T5 with an older 302 motor and bellhousing. I still use the old bellhousing and mechanical clutch linkage between the 5.0 and the T5.
Yea, they came behind carbed and injected motors in the early to mid 80's Mustangs. My dad had an '84 GT that was carbed from the factory with a T5. '87-'93 T5's that came behind a 5.0 from the factory seem to be the preferred T5 to get. Installing a T5 will be the same regardless of if it's behind a carbed or injected motor.
That may be true, but I would prefer to not have to deal with the wiring for the Fuel injection. Thank you Much! Exactly what I wanted to hear! Have a nice day folks!
Not much involved in converting an injected motor to a carbed motor just need the intake and timing cover and eccentric off an older 302. Oh and the front sump oil pan and pick up...OK and the distributor, you get the point. If its an 85 and up Mustang you get a roller cam and all the cam choices that come with it. And the 85 and up T-5s are World Class which means they can handle a little more torque (265 LB/FT). I think around 1990 or so they improved them again to 300 LB/FT. The older non World Class T-5 used thicker gear oil (70w). You will enjoy the 5-Speed. Mine allows me to run 3.70 gears and cruise at 70 MPH at about 2400 RPMs. WARNING: Stay away from the 86 5.0 Mustang and 86 and up 302s in other Ford cars and trucks. They often have the crappy high swirl heads and have true flat top pistons with no valve reliefs. They dont take cams with much more lift and the heads limit your power potential. After the early 90s most of the 5.0s were switched to the better piston/head combo I believe. 88 and up Lincolon Mark VII LSCs have the good 5.0.
Little clarification needed here: the crappy high swirl (E6SE casting)heads were mainly used on the 86-91 Crown Vic/Towncar/Marquis 5.0's. A few (very few actually) pickup and van 5.0's had these heads, 99% of these had the same E7TE heads the Stangs got. All had roller blocks, the pickup van 5.0's included, but with a flat tappet cam untill 1992 when the switch was made to(with the small C-Vic/TC/Marquis cam) roller cams (these were further upgraded with the F4TE cam in 1994 that was later used in the Explorer/Mountaineer ) And if you're going to rebuild or just need a core for a trade in, any of the 86-97 5.0's will do as they all had the same block, crank, and rods, but there was a switch to a weaker rod, the F2TE forging in 1992. The earlier C8OE rods were much stronger than these later forgings.
Hmm... Okay, so lemme ask this... If I were to take a V8 from say a mid 90's model and revert it to Carbed, what would happen to HP and TQ? I'm going to admit I've not done something like this before but I've got friends to help me, and Im just trying to get all the info I can so I can be well informed when I actually jump into it. With that said... If I were to revert a 90's engine to Carbed, can I still use the performance parts made for that engine, like the cams and heads, or would I have to go with older styles because of the carbed... this may seem like stupid question but like I said, Just making sure I'm well informed. *my way of thinking this question is because the performance parts for the 90s are made for fuel injection V8s and I would be sticking them in a reverted carbed and Im not sure if it would make a difference with said parts... you get the idea* Thanks!
I changed mine, it came from a 85 T Bird. It was throttle body fuel injection. Now it's aluminum intake and Holley 4 bbl. If it is a later model rear sump oil pan, you're gong to have to change it anyway, only front sump pans fit Maverick / Comets. Also will have to move dipstick to timing cover, if it doesn't have the flat place to drill or the hole already there, you will have to replace it with the early style cover. I'm running an electric fuel pump so I didn't need the hole for it. I'm not sure what you are asking about carbed vs FI performance differences. A engine doesn't know what is supplying the fuel to it. A good carb will perform as good as a FI system and can make just as much or more HP and torque. Some will disagree with me on that, and that's ok. When you buy performance parts, you buy what will work with what you have, or what you intend to build it to. I hear this garbage all the time about "Old Tech is not as good as New Tech". Fact is, you can make the old tech stuff run just as good as the newer stuff, it may just take a bit more tuning. Can't plug a laptop into a Holley 4 bbl and make it run different! Just because something is newer doesn't make it better. A lot of the old tech stuff can be bought pretty cheap right now, but I figure that will change as supplies dwindle and guys start buying it up for the "newstalgia" craze
What will happen to the HP & TQ are anybody's guess. That's going to depend on the intake and carb you choose. As far as what year engine to start with, that doesn't really matter (talking about 87-2001 years here) What does matter is the application you choose as a donor. Some are better than others in heads and cam. Ford built a half dozen or more different 5.0's in this time frame. The lowest HP/TQ was the 87-91 Crown Vic/Towncar/Marquis, next being the 86-90 T-Bird/Cougar, the 86-91 Pickup/van(flat tappet cammed with a roller block), followed by the 92-93 Pickup/van (roller cammed) 5.0. In 1994 the pickup/van 5.0 got a real boost in cam with the F4TE roller that was later used in the 96-2001 Explorer/Mountaineer 5.0. Lastly are the 91-93 T-Bird/Cougar 5.0 followed by the 87-95 Mustang 5.0 (also found in the Lincoln LSC Mark VII) then the 96-01 Explorer/Mountaineer motor. The only drawback to the 92-up motors are their weaker rods.
Have an 86 mustang 5.0 roller it has the crappy heads has an e303 roller has factory forged pistons by trw 66 289 intake holley 600 and goes plenty fast for such a light car
