ot dodge 360 from 85 same block as 97 ?

Soundguy · Dec 3, 2011

buddy has a 97 dodge with the 5.9l magnum ( 360 ) has a window in the block. efi.. etc..

we was gonna buy my beater rough looking but good running 98 dodge just for the engine.. but I enede dup selling it to work when one of our dodge 3500 work trucks sucked the injector pump thru the engine

anyway.. he found a carbed 360 from an 85 or so ? model.. and was wondering if block was the same. IE.. could he swap intakes and all and use the block?

thanks

Yup, the intake will swap. You want to keep the heads paired up with the block, because they are dependent on the piston domes, and they are going to be different across the years. The earlier engine probably has a Carter Thermoquad which is a great carburetor unless it doesn't work right, and then can be difficult to repair as it often warps. You can put a Rochester Quadrajet carb on as a replacement if you want, as long as you put the right jets and metering rods in it.

he was thinking of keeping it carbed and using the dizzy instead of coil packs. not sure what impact that would have on engine management cpu etc..

Almost nothing will swap as a direct bolt on between Magnum generation small block Mopar engines and older style engines of the same cu in size, not even the heads as the oiling system and pushrod angle is substantially different. The intakes can sort of be swapped but the holes have to be elongated a bunch and a set of spacers have to be used, but certainly not worth the trouble.

The short answer is ,swapping the engines is not that big of a deal, but the expense isn't worth it. An older 5.2 is minimal cost to convert to use in 92-01 Rams (about $200 in parts), but converting an older 5.9 to operate in place of a Magnum 5.9 will cost more (1800-2000 done right) than a good used engine.
I have done the conversions on both variatons of 5.2 and 5.9 engines so if you want more detailed information let me know and I'll send it to you in a Word file. It would take up too much room here.
Also, if the truck is an automatic and you want a functional transmission either forget about using a carb or plan on spending even more money.

sound slike a computer issue then!

Okay, bringing this up..Reminded me about another point. In Event of a disaster knocking out computer chips on autos and trucks? Would it Work to run hot wire to the Dist and Injection on early trucks to make a operable truck.?I doubt that Ignition mods would work on the engines Built With-out distributors as the blackbox would be dead? What about it? Car Doc? Dodge man? Any one?

I agree with this, the engines are very different. Just about any engine can be swapped into any vehicle, its just a matter of how much money. The engines are so common, why fight a difficult swap?

Soundguy · Dec 6, 2011

i think he was wanting to do it as the older 5.9 he found was virtually free.

don't sound like a good deal though..

Just running a hot wire to the injectors and distributor won't accomplish anything good as the computer controls the fuel and timing events. If you have a failure on the road the best thing to do is pull out your AAA card.

If you don't have a basic understanding of modern engine control systems, don't touch them or you will, at best gain nothing and at worst kill the PCM or some other expensive piece of electronics. You need a proper scan tool and knowledge of how to use it.

since the posters question pre-disposed a disaster that knocked out electronics. perhaps like an EMP..

I doubt whipping out his AAA card would do him much good.. unless he was trying to smooth a bubble out from under a decal

To some people, driving on the interstate in sub-freezing temperatures, with small children in the vehicle, and having the engine quit 20 miles from the nearest services constitutes a disaster. Since he didn't specify what disaster I didn't presume to guess what was on his mind.

Also, if he is close enough to the cause of an EMP that it damages his electronics (and likely shorts his storage battery), hot wiring a vehicle is probably the least of his problems.

he -DID- specify what type of disaster:

sounds like classic EMP to me.

I have to agree with those who say to get the right engine and put in there.

Why go old school? I did just the opposite in my 85 and went with a 95 engine. I liked the higher power and better reliability and better economy of the newer FI engines.

Swapping the other way would be MUCH more difficult. On MY swap, there wasnt much of anything CPU controlled. So it was just a matter of routing a few wires to power the CPU.

Swapping to an older engine, I doubt you would ever get any of the guages to work. And if it happens to be an auto tranny, it is probabally controlled by the CPU also. So that is another obstical to overcome.

Plus, he would have to do something different with the fuel dilevery. Because carbs dont lile the 50 or so PSI that his pump would be giving it.

He would probabally be money ahead to get a ~$500-$600 junkyard motor. Because even though the other one is free, it is going to cost WAY more in the long run to get everything working right again.

he should have bought my old/good running 98 dodge when i had it for sale for 1000$.. ugly.. but ran and worked. he coulda used it as a parter..

Ken, If it kills the battery, then none of our engines will work. I was talking about survival mode, not just my car quitting on the hyway. I definitely would not re-wire anything on my car as parts are delicate and expensive.My old diesel truck only needed a battery and wire to solenoid to fuel shutoff to run. Plus alternator to keep battery up. My be I misunderstood disaster day when EMP hit us? JY.

my old diesels will run with no electricity at all, once I get them started. figure some sweat and pushing down a hill and popping clutch.. or hitch up a horse team.

no fuel solenoids either.. just a stop cable..

SG, are you talking automotive, or tractor? I guess it doesn't matter much as you would still be moving.. Like some photos of Third world countrys tractors pulling familys and crops to market.My Bota has a stop pull line on it too..I sure hope it all is Moot point and we never find out about the day the Power all died??
