73 Duster

Why the hell not? If you have the time and fabrication skills, plus a solid 5.0 sbf, go for it. I think it sounds like a cool idea. The 8.8 is already a fairly popular swap.
I have all the time I need, I am retired and have quite a bit of fab skills as have been working/building different brand cars since the early 60's. I have been around for a while, and one thing I always think about is why do what everyone else is doing, doing something different is always a challenge and I enjoy the challenge.
