Good advice so far from everyone, and thats not surprising.
You will find that the people of this forum are the BEST resource you could possibly have for advice and info on e-bodies and mopars in general. And its a great bunch of folks!
A hemi cuda is the holy grail for many.
Me, I went a simpler route......
Having an unlimited imagination but limited checkbook I decided to find a fixer-upper.
I decided that while I could learn the mechanical stuff I needed to learn to make a car run safely, I would have a harder time doing bodywork and paintwork the right way (I have no patience for it...LOL).
SO I set out to find a car that was fair as far as body and paint.
I ended up with my 72.....fresh coat of paint, original floors, clean frame....interior was gutted but parts there, 318 engine (non matching) sitting in the engine bay but no idea if it ran or not.....underhood electrical a mess, not even a battery tray...LOL...no tranny or shaft.
But it had shiny limelight /sublime paint.
SO I bought it, trailered it home and with the help of folks here (that's an understatement for sure) I had a runner in a few months time.
I never installed a tranny by myself in my life.....but I have done it twice on this car (longer story...LOL)......learned a LOT working on it so far and I am sure I will learn much more in the future. Since then I have been slowly making changes/upgrades. One day a hemi or big block may be in the cards but for now I have a lot of fun with my tweaked 318.
If you have the bucks to go full bore from the gate, do it! But if not, don't let that slow you down. Start small and work up.
While I really love driving my car, I think I get as much fun or maybe more out of wrenching on the car myself, even with its ups and downs and occasional frustrations.
Good luck, and hope to see you posting pics of your car here soon!
