I have seen people put LA pans on magnum engines. So I dont see why you couldn't put a magnum pan on a LA engine. I have a 91 Dakota sport with the cab and bed from a 96. I built this dakota because every body wanted 3 grand or more for rusted out A bodys.lol. I pretty much got my dakota for free. I call it my pro junk yard Dakota because I have body parts from 5 Different trucks in it.lol I am running a 2000 5.9 magnum engine in mine. But its not stock. Has stock bore and stock stroke though. Best pass so far has been a 11.24 at 115 in the 1/4 and 7.15 at 95.86 in the 1/8. Best 60 foot has only been a 1.57 so far. Spining of the line. I am running the full caltrac set up and need to do more tuning on the rear-end. I am using the rear axle out of a 96 Ford explorer. Which was pretty a drop in. Just had to cut off the factory spring perches and sway bar mounts. Then weld on new spring mounts and shock mounts. I have weld pro Star 15x10 wheels with 5.5 back spacing. Tires for now are hoozer 28x9x15 slicks.. AJ like what has been said you will have to weld up some mounts to put the LA engine in the Dakota.
Well, I finally went to see that free dakota, and as you might have guessed, there is really nothing left to work with. I'll keep tho.
I'd like to thank everyone for their comments, ideas, and especially for the inspirational pictures. Adios for now.
