In my search for a T top regal roller I ended up with a 85 grand national that I am planning to LS swap and possibly add a single turbo to. The car was not running when I got it, it is rough and getting a frame off restore. I threw a spare fuel pump in it and got it to at least move under its own power but then dies. It has around 120k on it and probably needs to be fully rebuilt if I had to guess. I am going to throw a new fuel filter, plugs and wires in it so I can move it around for the time being and then maybe sell it. From what i have read, these engines have lots of gremlins in them and are hard to find parts for. Not to mention 1985 technology vs modern, having a dependable engine that I can trust for long road trips in the middle of summer heat with AC is huge to me. Is there any reason at all to put any kind of effort into this engine vs swapping it for a engine and trans with all of the parts to bolt it in that are sitting in front of the car as we speak? I'm pretty sure my stock 5.3 with nothing done to it would kill this hot air engine even with upgrades, maybe I'm wrong?
