Made a new friend in the hobby today who was active in the golden years. He told me about his cars [all long since gone]. LS-6 Chevelle, A-12 car, L88 Corvette and an L78 69 Camaro...probably a few more. He did business with Motion and Byrne Bros Chevy...
He told me his LS-6 car had aluminum heads when it was new
I know, it never happened...but, since you folks enjoy a lively discussion I thought I would mention it. He referred to the engine as an LS-7...
We are going to meet up pretty soon...he says he has photos and info from way back when...should be interesting
