I am trying to find the original muscle machines 1:18 have not been unable to find at Wal-mart. Does anyone know who makes them or a 800 number?

Hi & welcome to the boards.
Wal Mart hasn't carried 1:18 scale Muscle Machines for quite some time now. In fact they don't even sell the 1:64 Originals line anymore. All they have (sometimes) is the "Nascar Muscle" 1:64 line, which in fact is sold under the "Winner's Circle" name brand.
To be honest, I'm not even sure if MA (Motorsports Authentics), who own the Muscle Machines name now, is even producing any 1:18 scale MM product
nowadays. If they are it would probably be Nascar-theme anyways.
You may get some replys here but you would probably get a better response over at Joe's Diecast Shack. There are alot of larger-scale Muscle Machine collectors over on that site. www.joesdiecastshack.com
Good luck with your quest.:)

hey floyd frog,
you're right about the nascar theming.
there were some 1/18s put out through RCCA in 2008, but they were all nascar themed, or had John force paint jobs.

e-bay normally has a selection of 1/18s.

I remember about three years ago I was in a Big Lots store & they had a ton of 1:18 scale Originals. Stacked on the floor at least 4 feet high. Lots of different castings, some Stars & Stripes, a few Raw, etc. I've never purchased a 1:18 scale car only for the fact that if I do, I know I would dive head first into them. Looking back, though, at $9.99 each, I probably should have picked a few up.:)
