 Subject: Engine swap 3.9V6 magnum to 73' 318V8
IP: Logged
Message:
Got a question. I have a 1992 Dodge Dakota Extended Cab with the 3.9liter magnum. The engine blew and the local trans shop which is also a buddy of mine said to just drop a 318 in it. The 318 is from a 73 Dart with 1 barrel carb, and the 3.9 was fuel injected. I also know that the 360 is externally balanced and the 318 is internally. I have a 360 engine trans and torque converter but I know the 360 tqcon. wont work with the 318. Does anyone have a 318 tqcon. they want to sell to me. also This 318 Im putting in it NOW has an edelbrock intake ane 650 edelbrock 4-barrel carb. Also can anyone tell me any other problem/problems I might have with this engine swap? Please let me know! Also I need Headers to work with this engine and this truck. If anyone can point me to the right direction.

Also What trans do I have in my 92 Dakota with the 3.9magnum and will the 318 bolt to it. I done measuring and drawn on carboard the bolt pattern and they seem to be the exact same. What opinions do yall have for me? AND will the 318 Torque Converter work on that trans and if the 3.9 tqc is not balanced will it work on the 318?

you have an a500 tranny the 318 will bolt up but i wouldnt hop up the engine at all because i dont think the tranny will take the abuse. you'll prolly end up with problems down the road.

Just a follow up I got the engine in the truck and also found the numbers on the tranny and it turns out to be the 518 trans so I knocked the weights off the 360 converter and used it and it works. Thanks for yalls help!

Simple, instead of the 1970s model 318 get the one that came in a dakota, motor mounts are similar, computer is the same and you wont have to worry about your rear end.

The A500 is a 904 with an OD unit bolted to it.
The 904 /A500 can take loads of abuse, it was used in 318/360 p/u's & vans for years.
I don't understand why a 92 & up 318 wasn't used. Much easier and a better engine to boot.
And 318s came with 2bbl carbs.
