great question !! 19701-1980 saw some of the best racing  inovations ever--

I.E sonny seamon cars ,  troyer chassis ,  flemke  suspensions  , many , many ,safety improvements--

really good racing from better handling cars-

---------BUT---------

liked 1960-1970 the best --" backyard engineering" , guys coming up with their own way of handling better and going faster --wrecking yard parts ( thanks  clint osborn   !!)--run the same car on asphalt or dirt with some changes ---

coupes  & sedans---------sorry--showing my age !!! 

blessings ,all !!
