Had it out yesterday. Sadly I might still sell it as I really want to drop my 500 inch big block into something. I think this old car and 7 grand should get me what I am looking for. I drove this 100 miles yesterday LOL.
Define ruin it. Some would want you to leave a car original, others argue its your car do what you want. I think it would be a awesome site to see and an even more enjoyable car to own than it is.
Just don't "bling" it and you and I are good ....do it!
But your going to do that anyway in any car you put that monster engine in.
I would also add a gear vendors unit. That car is dying for a monster 440, don't tub it, a nice resto mod would be awesome.
