1970 mack R400
Info on the above Mack was owned by local contrator, he had 2 of them and some real other big equipment equipment long since sold.The truck had a quad box with a scandia engine.
my granddad was a mack dealer in canton ohio many years ago and as a teen I spent my summers working for him. I remember him selling R400s and some of them were gas engines, had 440 Dodge engines. those were the days.............................
