You joke, but I wanna do that one day. It makes no sense, will make no power, get terrible fuel mileage lol...but they sound so good

I think the two stroke Detroits are as cool as can be.

When you consider a 4-53 is only 212 cubic inches, that’s pretty darn impressive they made the numbers they did, being put in trucks with a gvwr of 30k, or combined to 60k lbs.

Brochure cuts below are from 1980, the 2 stroke Detroit platform was already 40 years old, but wasn’t far behind the new 8.2 fuel pinchers. Despite being less than half the displacement.

Oh wow! I've never actually looked up power numbers, just knew you basically have to hold them at redline to make power

It was a machinist at a military installation, Yakima Training center in Selah. I fell in love with those 6-4-53s that they put in a lot of those rigs not only did they sound bad to the bone. They really hauled butt too, cause they were both turboed and supercharged. I hated the 6.2 in the C20, but now that I am understanding it, I love it. It is not powerful, but now that mine is running I use it all the time, and I did haul a load up a steep hill the other day 8000 lbs, and just kept my foot in it, and she did great. Only thing that hurt my feelers working there is all the machine guns and etc. I had to cut up, they watch em' close, so I couldn't sneak one home.
