How robust is the aftermarket for classic mopar muscle cars?

I have restored a few Mustangs in the past, and there are a ton of sources for aftermarket parts.





Are Mopar parts easy to come by as well or am I going to pay a premium for every single thing? What about aftermarket performance engine parts for a 426 Hemi?





I am considering buying a 1970 Challenger or Cuda, but the wife wont let me mortgage the house for an intake manifold.





Thanks!|||As you surely know, restoring muscle cars isn't cheap if done properly. If you plan on restoring a '70 Challenger/Cuda that originally had a Hemi, a beat up project would cost well over 50 grand. But you probably want to take a base model and turn it into a Hemi clone, which would be a much better idea for cost and fun.





But honestly, if you're planning on doing an extensive resto it will cost A LOT for sure on a '70 E-body. Very few guys have custom built 426 Hemis cause the stock power is usually enough (465hp, 490 torque). A new 426 Hemi crate motor is 13 grand, and a vintage 426 Hemi would be at least that.





If you just want a cool E-body to drive and have fun with, look for a clean and running '70-'74 Cuda/Challenger with a stout 440 for 20-30 grand. That's what I plan to do in the future. Let someone else put the $$$ into it unless you have enough to do it comfortably.|||Parts are certainly available for Mopar products, but they are significantly more expensive than for either Chevy or Ford.


As an example, a baseline high performance engine assembly from Summit Racing runs around $4000 for either Chevy or Ford, and close to $8000 for Plymouth/Dodge.


As a rule, for building a driver - stick with what is popular. For collectability - stick to stamps.
