Putting aside the famous muscle cars for a moment, like the Boss 429s,
Super Bees, there are probably some quick rides that have been overlooked
like the Cobra Jet Torinos. Any other lesser known or overlooked cars to
Gran Torino CJ 351 (http://www.thefreedictionary.com/_/viewer.aspx?path=4/43/&name=Gran_Torino _500px.jpg)
SD 455 T/A (http://www.sd455.com/transam.htm)
74' AMX 401 (http://forums.skylinesdownunder.co.nz/attachment.php?s=&postid=348160)
I think the reason that they are overlooked is that the lines are quite in part of current classic tastes. Which is part of owning a classic, it has to look the part. Mid to late 70's and early 80's seem to be a dismal time for cars but may be they are on the verge of becoming classic, at the moment they are probibly still seen as cheap old cars may be in 5 years they will be proper muscule classsics like a 69 z28 and 71 stang. I think in terms of style then the AMX has the most out of that bunch. I have driven a sd455 i think it was a 73 which i prefer the styleing, im not sure if it was an origional or a sd455 put into a 73 TA. Post 72 seems that the tree huggers got hold of the motor industry by suprise so for a number of years there wernt that many ways to meet all the constraints interms of smog, reliablity, driveability, cost etc and produce the power.
They are powerful vehicles in that era, and those are good looking vehicles, I say go with Cinqyg and realize you can buy them cheap now, and that maybe someday they will be where they belong, in store with the classics. I especially love the 455, then of course I love every year F-body to some degree or another.
Yeah, these versions will slowly appreciate over time. Their numbers have
fallen over the years because people thought they weren't worth anything so
that should help the value of survivors. I would say even plain Javelins
are going to rise.
I put a 73' shape Trans Am here with a SD 455 engine. Not many of those SD 455 cars were built.

Also in the smog era the 71/72 GTO with 455 HO no lead engine and 4 speed. A pretty quick car that falls outside the classic 1964-70 GTO years. Looks good with the honeycomb rims that came in around that time.
