ok, I am not the smartest when it comes to dealing with engines, i know parts and what not but engine swaps, and horsepower combonations, im an idiot. by the way, im only 15, if that makes a difference. ok, with that out of the way. my bud "had", a 92 mustang notch back with a 5.0 302. he "had", beacause he wrecked it today in the rain, its not to teriblly built up, it has a "mild" cam, throtle body, throtle body spacer, bbk headers, cold air intake and what not.ok, so it was just rebuilt lees then a year ago, and he just got a new transmision like a month ago, wiring harness is still all together. so here comes the question, how hard would it be to swap his motor into my 68 cougar???? would it be worth it???? o yeah, at the track his slips say he ran a low 14 sec in the quarter mile. so, please give me your honest opinons on this one. thatnk you guys.

my old 68 302 is already out, and both my car and his are automatic, uhh, what else... what other information do you guys need to know to see how hard it would be etc.... both 302's 5.0 , his is a H.O or high output. My other good freind casey pulls motors quite a bit, has already pulled a 94 5.0 motor and wirning harnees, rubuilt it. and put it back, it started, runs fine. so, i need help, thanks again

motor swap itself should be simple, same block. not sure if the new tranny would have the same mounts as the old, but you could run the old trans with the new motor (forgive me if that's what you were intending). however the wiring harness stuff....i wouldn't touch with a 20 mile pole. Just because you had a buddy do it doesn't meen he'll be around to help with yours. Friends don't allways come through (the real good ones do) and you don't want to be half way into a project with an empty wallet, no running car, and no $$ to pay someone else to finish it up for you.must be nice to have a 68 coug at 15...

yeah, im scared of the wiring harness, like you said the swap would problly be easier than the wiring harness, i wasnt planning on using his tranny as well, but if it would work, it sure would be nice. thatk you for your reply, and yes, i LOVE old cars, i saved my money sice i was like 10, came up with 500.00 bucks, and talked my dad into letting me buy it, it is a really straight body, thats what caught his attnetion, and when I told him i was saving up fpr a streetbike, he almost forced me to buy a project car, my plan worked, i just wished he worked on it with me more, like a father son project car, e used to rebuild motors, and eventually got tired of it.Thanks again

I'm itching to do a similar swap myself but can't work the courage. Phil, I say start doing research. Figure out which sensors/computer pieces you need to run the engine and how they're wired in. When it makes sense to you then you'll have an idea if the swap is something you're comfortable with.Worst come to worst you do it over Christmas break and end up riding the bus through January and Feburary until you get things figured out.

this has been done many times and shoudlnt be hard but i can tell you that you need to find someone who is compotent to help you. youre motivated and thats good, it seems like you are apprehensive, thats good too if you know what not to tackle. you will need to use the computer and wiring harness out of the 5.0 car. if you have a c-4 and you plan on racing it later, thats the trans i would use with the 5.0. dont think about modifying it if the motor is in good shape. just do the swap and you'll learn a lot from there. you'll need a fuel pump if you keep the motor fuel injected and i think you'll have to run a return line. if you decide to go with a carb the swap will be much simpler and it wont cost you as much since you'll already have all you need. dont be afraid of the 5.0, its just a 302. the long block will swap right in with the only major difference being the fact you'll need to use a 50 oz. flexplate to match the 5.0's balancer. dont screw this up by using the wrong flexplate with the wrong balancer. and remember the 5.0 has a 351w firing order, not like the old 302. this swap is easy and will pay off bigtime but get somebody who knows what they are doing to help you. your car will be quicker and you'll have a great foundation to build on. ------------------

Parts houses like Mustangs plus have the conversion parts available (like harnesses and the like)take your time - dont rush it, and you should be fine. Mustangs plus is just a starter (and a site sponsor) but if they cant help you other places will. they want to sell you the parts you need so they should bend over backwards to help you. I think its a good idea myself and I am considering doing an EFI conversion myself (after years of hating EFI I wonder If I could live with it in my classic) If nothing else the smooth idle and better gas mileage should be worth it. ------------------

Phil,
Try not to be too hard on your Dad.... for many years I had hard feelings toward my Dad because I thought he should be helping me with my car projects or at least asking me "How's it going?", but he never did. I thought all kinds of thoughts as to why he didn't help or guide me in my projects. But now, years later, my Mom tells me the reason why he didn't assist me with any of my projects was that he was afraid of making a decision or suggestion that wouldn't turn out good... and thus, look bad in my eyes. It wasn't that he didn't want to help me, but rather he was afraid that his actions would let me down. I suggest you share your project progress with your Dad, but don't be disappointed if he doesn't give you a direction to go.... it might just be that doesn't want you to come back pointing a finger at him. I've also had friends of mine (who are dads themselves) tell me they don't play computer games with their kids because they simply don't not want to "look stupid". Think about it. Life's too short for you to hold a grudge against your Dad - he's still your Dad and he won't always be around.

Thats some Good advice Ryan, thanks. i dont hate him or anything.
anyways,
Toronado3800; im defintlly in the research stage right now. im just rying to find out every little detail i can.
chip67; thank you, i nned all that information.
indyphil; i will defintlly check Mustangs plus out.
chip67, you said ".....decide to go with a carb the swap will be much simpler and it wont cost you as much since you'll already have all you need". do you mean all i have to do is swap intake manifolds and run that efi motor as a carb. motor instead?!?!?
would that be worth it if you can?
and how much would you guys pay for that 92 efi, h.o. 5.0 ?
thanks for the replies , keep em' coming

thats what i did. i didnt have the choice, my motor came out of a junyard wharehouse on a pallet. but i dont by any means regret it. the car i have is lighter than most 5.0's and old enough i dont have to worry about passing the sniffer. even though i'd like an injected twin turbo motor if i was rich, a poor man gets a carb. im not a huge fan of automatics, i like to drive my car, but i can tell you that with a stock roller motor and an edelbrock intake/holley carb i could already spank the injected cars just because of the p/w ratio. you can keep all the injected stuff, the harness and switch it over later if you wish. dont look for a big profit if you can sell the efi stuff, especially the manifold itself. just hang on to it, all of it. ------------------

I'd say $1000 for a low mileage complete hotrod injected 302 with harnesses and pumps is fair. IF you're going to pitch the computer and go the carb route it still isn't the worst of deals. I think I sunk $2700 into my motor by the time I bought pistons, paid for balancing, and all.

Try a search in the Mustang section and you will probably pull up some stuff. I think I remember seeing this a few times. I was going to take the stuff out of a early 90s Cougar to do this swap because I didn't seam all that difficult but the guy sold the car about a half hour before I got there.------------------

Well, im sad  , the block is cracked as well as everything else. the motor is junk from what the mechanic said, when he hit the wall, i guess it drove the motor mounts into the firewall a little and cracked the heads. ruined som other neccesary parts, so, its not going to happen, which makes me kinda frusterated. i really was looking forward to a swap like that. anyways, my 68 302 is going to be rebuilt for free by my neighbor, who teaches a class at the local college, (he has a 70 parts mustang, a 65 fastback, a gt40 kit car, rebuilt all the motors) he is going to show me step by step, do all the hard work while teaching me how to rebuilds the motor, so that will be nice. thatnk you for all your replies, i really wish that his motor want that bad, but you can actually see physical damage.
thatnks again , for all your replies
Phil

That sucks. Another deal will come along, thats the only silver lining in the way Mustangs and Camaros lead the world in one car vs tree accidents.
