Was down at the bank this morning when a local 44o Duster from around 1970 came past with the headers open. Was at it's minimum idle which is probably 1500 and cam is so radical it was getting full compression firing impulses into the exhaust that sounded like gun shots. Making MAYBE 600hp and maybe 6-8 mpg. Miserable to drive as he had to keep clutching rather than lose any rpm and die. Out at the shop is a 1970 Camaro with an LS 9 that is 650+ hp stock (it's modified) with an automatic that idles at 600 rpm and gets 25 mpg. His wife could drive it to the grocery store. The nerds have beaten us hot rodders.
