Every 2-stroke Detroit is supercharged and many are turbocharged. The supercharger (nee blower) isn't for power. It's for normal operation. Ever wonder why superchargers are rated such as 6-71 or 8-71? Because that's the Detroit Diesel engine that it originated on.

6 or 8 cylinders, 71 cubic inches a cylinder

We had one MCI with a 12v, several with the 8v, and one shorter MC8 with a 6v.

Acceptable power for their time in history, but nothing compared when we got our first Prevost with a Detroit 60.

As per the Blastolene website, that is a gas powered 702 ci GMC V-12.

Yup, and later, 6v92 and 8v92 for the same reason.

The us army has the 8v92ta in a few trucks so if 1,400ftlbs is only useful then I think you are crazy.

You know what they say:

Old truckers never die, they just get a new Peterbilt.

I spent 30yrs rebildin all types of diesel engines, the 1st a 6-71detroit, and the last one a 2cycle detroit, (kinda got a soft spot forem) history says 1st engineered around 1934, 1st mass production 1937, called GMC for Greyhound bus to get over the Denver mountain passes, also same time for Marine use called GRAYMARINE, it is said that WWll was won by the 6-71 engine, trucks had a sound that all 6 cylinders fired in one revolution, at 60* intervales, so smooth.

YIKES!! a 20V-149,, thats a V-20 cylinder, with 149cu.in. per cylinder, DUH, (recalculating), 2980 cu.in. thats 181780 CCs, and a mess -o-litres, youd have to start with a locomotive chassis, to hold the static weight. you might reconsider choice.

seein how we are completly off the charts here.

the largest diesel engine ever built, goes into a Korean container ship, 100,000HP,, 200,000 ft.lbs torque, Yeah probably to big for a street car tho
