'1970' Road Runner '383' vs. AMC Rebel Machine '390'

I do remember back in 1970, a Service Manager for our local
American Motors/Rambler/Buick Dealership {Geis Motors} had a Rebel 'Machine'.

The car did sit real nice, kind of high as it had 'special' suspension and
15" E-60 x 15" tires.

And, the exhaust was loud. The 'Machine' did sound real good.
