Thank you Barracuda Dan for these pictures.
Note Injection. Mostly in the early year of the seventies, cars sometime ran in GAS Class, like this S&M car and former Chackmate SS Barracuda. Here in C/Gas and 404 cuin Hemi (NASCAR Crank)
Good eye...also I believe in 1970 some 68 super stockers were running in the new Pro Stock class and Modified Production Class as well. Great pictures.
