3.9 Stroker

Unless it's a Shelby Dak, V-8's are not a drop-in at all until they switched to the body like the red one above, that's why they changed the nose. T he stroker crank is probably more than it's worth just to get some more torque, but it would work, if it even needs a crank. I have a '90 TBI 3.9 that was locked-upwhen I got it for parts, soaked the cyls. with nano-penetrant for a week, then put compressed air in the cyls. & I got it to move. Now I can turn it over with a ratchet. I've seen those systems start dumping fuel all of a sudden, wonder if they're washing off the oil, then rusting up if left sitting too long...
A la v8 fits fine. I swapped two 87s. one with a 904 and one with a factory 5 speed the one with the 904 took a friday night and all day saturday and it ran and drove. That includes pulling the engines and trannys from both vehicles the dakota and the donor diplomat. I had a drive shaft in my pile of driveshafts that fit fine. Used diplomat throttle cable and kickdown linkage. I cant remember what exhaust manifolds I used. probably D/W truck or the diplomat manifolds. Short spacer and a mechanical fan cleared the factory rad.

One of the easiest swaps I have ever done.
