1966 Valiant...should I part or fix it?

I'd keep it and do all of the things you mentioned that it needs and make it into one badazz little car...but that's just me. Sounds like you can get some of the items it needs for free and purchase some items along the way until you are ready to cut out the rust and replace the floors and frame rails...but that's just me. In the mean time, find a nice little smallblock to warm up with a few goodies, get some Schumacher mounts and a couple other items and get it setting there to make the switch when you have it all stiuched back together... but that's just me!!! You do what you want, but it sounds like a fun little project, Geof

Putting 5 or 6K in a 2 to 3K car doesnt make much sence to me, not to mention all the time and labor re-doing the the frame, floors, quarter etc... By the time you got the frame, floors, quarter finished you could have bought a decent 68-69 dart or cuda body.. Uni-body rust issues are a totally different ball game than full frame cars.. On a 66 you don't have to use Schumacher mounts to install a small block... Based on what hes said about it, I wouldn't fix it...
...until I saw the subframes. They are completely gone where the upper control arm bolts up. One of the uppers is actually almost broke loose so I can't even drive it. The rears are a little thin where the rear springs bolt up in the back. Typical places... but do I want to spend the time to fix it? Is it worth it? It already needs front floors and one rear floor, passenger side front inner fender, quarter panel work,new springs, shocks, etc, the seats and carpet are shot. It needs alot.
