I used to work on commercial fishing boats and full throttle was called "smoke holing it". No engine mods were needed on a WWII era 6-71 Detroit diesel to make her smoke, just punch it.
That being said, the guy in the truck video is an ass.

I know. It was an attempt at subtle humor as a response to and to tweek the ecowackos. Maybe it just goes wrong.

Ever had a 671 run away?

Gray Marine, of course.

Scary.

Lucky for me the safety shut down devices (which I *think* are something like spring loaded plates which are rigged to close when the incoming air velocity exceeds certain amounts) did work.

It was screaming there for a while...I thought it was going to blow up.

Years later I was offered a pair of those type of engines, complete with crash boxes but declined the offer.

Now if they had been 471's (which can be good for 30-35ft boats) or 271's which can be good light-plant engines...or 353's which are used in a lot of seine skiffs, or almost anything other than those 671's which at one time were very common on the West coast, then it would have been worth it to take possession.

Can’t beat the way a Detroit Diesel SOUNDS!

Years ago when I was long hauling for a living, I used to see this one rig in Texas on dark nights that had at least two feet of flame coming out of both stacks. It was neat because you could tell it was him when he was still two miles away. I unrolled my window to listen to him go by and it sure sounded like a 6-71. I have no idea where he hauled out of or where to but I would generally see him between Midland and Abilene.
