I agree with you completely DoubleEagle. It's to bad things aren't fact checked before it's actually able to be posted to the internet. I'm also from Missouri and I generally don't believe anything unless you can actually show it to me. Just thought that I would make the things I've found visible so no one travels down the rabbit hole to nothing. The only thing that I've actually found to be true is when people change little things in the 5.9L 6BT Cummins. Like changing intake and exhaust to get you a little more power (normally less than 50H.P.) But I do like how the 2-Stroke Detroits sound not much better in my opinion.

Go buy it. Just remember issues like cracked heads, rare parts. I wouldn't try to tow with it. If oil hasn't been changed recently, get oil sample. Sure it can be done, but good luck trying it in a coach with serious weight many btdt over the years.

Thanks Chessie4905, who are some of the 2-Stroke Detroit Diesel experts here in the states that I might be able to get into contact with? For some reason there seem to be a lot of 2-Stroke Detroit Diesel experts in Australia I really wonder why that is. I know that there is Shafer Diesel in Tennessee, Leid Diesel, Industrial Injection, and maybe Scheid Diesel but I really don't know if any of the above really specialize in the 2-Stroke Detroits. Be nice to be able to contact the companies that do pulling or drag racing events or marine boating applications with the Old Detroits as I'm sure there is a wealth of knowledge there regarding what works and what doesn't.

6-110 is a VERY heavy engine-like as much as a 12V-71. Externally the 6V-71 and 6V-92 are virtually identical. The only way you can tell the difference is by the 92 on the block.
The is no such thing as a 4V anything. There is a 4-53 and 4-71.
I think it is time for all to consider switching to a modern 4 cycle engine. 6-71 can be replaced with a Cummins ISB (280hp 660lb/ft torque [HD rating]). 6V-92TA can be replaced with Cummins ISL (450hp and 1250lb/ft torque). Good Luck, TomC

The more horsepower on the DD 2 strokes, the more heat issues.

FWIW 21:1 to 25:1 is pretty standard for the 53 series and are wet like 92 series the aluminum blocks the liners are pressed into a heat block sorry little engines short life but they will make hp and noise

Have they figured out how to make those Cummings turn backward.

903 can turn backwards.

On a V730 or V731, they make a reverser gear. Right hand engines that have run through the V730 with reverser gears is the Cummins ISL, ISM, ISC and Detroit Series 50. Cummins 903 V-8 is able to run left handed. I know of at least one 4106 that has a Cummins VT903 running through the V730 directly. Good Luck, TomC
