Hello,
This is my first post, so thanks in advance. So I acquired a 1994 Dodge Van with a 318. The engine is toast, it threw a rod and the block is dusted. I’ve located a running 318 that was pulled out of a wrecked 2002 Dodge Ram truck. I did some research and I’ve found that the long blocks are the same part number at Autozone. I did notice however the starters are a different part number. I’m not very familiar with Mopars, so I was looking for some advice as to whether I can use the 2002 engine in the van and what are the major differences between the two. Will it bolt right up to the transmission?
Looking for some advice and guidance, thanks!

 

If you are going to use the long block I would think you would be ok. All the ancillaries would need to be swapped over from your motor in order to work with your ecu. Your motor is obd1 and the 2002 is obd2. Another thing just occurred to me and that is does your engine have egr?

 

As jefferson said, long block is the same. Use the intake, flywheel and brackets from your motor. Buy a new water pump.....

 

The van is equipped with EGR.

 

You will need to use the intake off the old motor, The 02 didn't have it. Might want to do the plenum fix while you are at it.

 

Ok will do. Do you know of any links that pertain to the plenum fix?

 

In the 2nd gen ram section, there is a stickied thread "Be all, End all Plenum Thread." Or something like that. More information than you ever wanted.

You will need the passenger side exhaust manifold from your original engine as well, as the newer ones don't have the provision for the EGR tube.

 

Hey I really do appreciate your help, I was able to find some YouTube vids and a new plenum kit made by Hughes. I’m going to check out the thread you recommended.
I hope to get this van back on the road soon, I’ve got quite a few things on the to do list, the poor thing was sitting in a field totally exposed to the elements for about 10 years down here in San Antonio, TX. But it was once an awesome machine. It’s got the high topper, and that’s the only reason why I’m putting any effort into this project. Thanks again!

 

So, sun baked, instead of rusted out. Pics??

 

UTawesome performance has a plenum plate that is less expensive, but I don't think it is a kit. That APS kit looked pretty good if they are still in business.
