Will a 88 Dodge Dakota V6 flywheel work on a LA 318. I want to bolt a 1973 318 up to my Dakota V6 5 speed.
3.9 and 318 are both internally balanced. You should be good to go, just make sure the 318 crank is drilled for a pilot bushing/input shaft clearance. Edit: As long as you're not using the computer controls on the 318. That flywheel only has 6 pickups for the crank sensor. If you're carbing it, you're good.
I believe the 3.9 flywheel will bolt up just fine to the 318. However if you're going to time the 318 off the flywheel you will have to get a 318 flywheel or 5.2. 6 vs 8 on the timing. If you're going to run a distributor with its own advance and not worried about the computer controlling the timing you'll be fine.
Yep, works fine, I needed one for the kids carbed 318 in his 70 duster, went to the pick and pull and grabbed one from a 3.9 dakota, just machined and put it together! Been in there three years now.
I did this backwards.... I put a 5.2 (318) flywheel on a 3.9 in my 87 dakota so I could use a NV3500 transmission..... On another site, I have seen others do exactly what you are doing, and it worked. But keep in mind the NV2500 trans, is weak. A little off base, but with a 87-90 dakota, your biggest problem is going to get the motor to clear the radiator. In short, I believe there are 3 ways..... 1. As Shelby did with the 89 shelby dakota's, make a special crossmember and move the motor, trans back. Then use pusher electric fans in front of the radiator. 2. Use a magnum serpentine belt system, along with pusher fans..... This is what I am doing on mine. 3. Swap out the front end for a 91-96.... Dodge moved the radiator about 4 in forward to provide clearance. Below is a picture of a 3.9, and the factory radiator. Figure the V8 will add 4.5 in. to the length of the V6....
Wanted to add, if you want any info on what I posted above, let me know, and I can send additional pictures, and links to others.
