Well, been a while since I had anything to update you guys with -- This project has taken a bit of an interesting turn :)
I just picked up an LQ4 6.0L to drop in instead :D Still planning on going with the NV4500 / NP241, but I got a smoking deal on the engine, and simply couldn't pass it up :D
Once the snow melts again, and I get my 6.0L here, I'll update with some more pictures :)
