What is a good old muscle car to restore? that wont empty my wallet?

Me and my brother in law are lookin around for a muscle car to buy and rebuild, Preferably a car in the year range of 60's to early 70's we already have a 66 El Camino, but its our drag car and its not even close to street legal at 10 seconds. so we are just lookin for a car that is a some what reasonable price to buy and work on. any suggestions? our main interests are anywhere from a chevelle, to a camero, to a dodge demon. but any ideas will help. So if you have some info on what they are going for in poor condition to rebuild let me know please thanks for you're time

P.S. I live in montana, if you have information on prices around here please let me know. but anything helps

First off, I agree with you, any car that is set up to run a 10 second quarter is hardly what I would deem "street legal" no matter how many license plates, mufflers and stickers you might have on it.

'60's and early '70's muscle cars are pretty much a very subjective choice - for me, it would be a '69 or '70 Mustang Fastback but I suspect that you prefer a Chevy, in which case, a Camry, Nova or Chevalier come to mind. Parts are readily available for all of these vehicles.

Get a Duster

definitly a 1968 camaro.

Try a different approach and go with a '64 Ford Galaxie with a SOHC 427 and a Hurst four speed.
I had a '62 Galaxie 500 with a 390 HP with solid lifters, factory headers and a 4 speed and it went 105 in the quarter.

If you prefer GM go with a Chevelle.
