So I recently picked up a 5.9 Magnum, originally just to use for mockup purposes as the original motor for this project is still at the builders and is going to require about $5k to finish the way I want, which I'm saving for but probably wont happen this year. I decided to freshen up the junkyard motor for now.
I think these are Dakota manifolds, but they were free and I'm going to see if they fit in the bay flipped around. At this point the project spiraled, I ordered some V-band flanges, 2.5" exhaust pipe, and a eBay GT45. Next order is a Holley Terminator X and some weld in injector bungs. My plan is to use this motor as the test mule until my TFS headed 408 is built, then swap the MPFI and turbo setup to that motor.
