The turbocharged 350hp 8V-71 is the main reason I wear hearing aids today. The turbos were added to the 318 hp 8V-71 making it a 350 at the request of Consolidated Freightways as an aid to making better time over the Rockies from Cheyenne, Wyo. to Ogden Ut. At altitude, a 318 is a gutless wonder and at least one gypo trucker turned the governor up to 2800 so they would make a reasonable amount of power. This was not a secret.
The one I drove blew a gallon of oil all over the deck plate ever thousand miles. In winter with ice and oil all over the frame it was a dicey deal to climb up up on the frame to push the defrost button on the refer unit. In the 70s the 8V engines came with 2-piece pistons which no doubt contributed to the oil consumption. Not much power by today's standards but we were only grossing 80,000 except Wisconsin, which was 73,280 lbs. There was a sign in the drivers room that said, "Do NOT cross ANY Wisconsin scale loaded." I hauled 80,000 lb loads of fruit from Yakima, Washington to Appleton, Wisconsin on I-94, and US 10 in Wisc (no scales). Then drugstore sundries back to Seattle on I-80. A round a week. I was very glad to see that 350 engine come along. I had a whole afternoon free in Seattle after that.
The 350 solved the altitude problems but not the oil consumption and the 92-series was supposed to be a much better powerplant but by that time I had moved on to 350 and 400 hp Cummins-powered rigs.
