Talk:Detroit Diesel V8 engine

This page is sparce! Can someone please pop the hood on a Step Van and post something

Hummer EV
Why does this page reference the Hummer EV, a vehicle that isn't offered with any type of combustion engine, let alone one of the antique indirect-injection diesels? Chalmondley (talk) 19:10, 8 August 2022 (UTC)

Picture
I added the picture of the 6.2 in my 1984 GMC Sierra Classic Longbed... its not very clean but hey, its here now and the thing has seen a lot of work! Sixthstar (talk) 01:08, 30 April 2008 (UTC)


 * It's all we got until one of us rips out a 6.2, cleans it up and takes a picture of it.--Dana60Cummins (talk) 17:38, 29 August 2009 (UTC)

Step Van/P30 application
I know several applications of the engine are missing, specifically the P30 (or step van). There were also some naturally aspirated 6.5L crate engines used by many of the companies who owned fleets of P30s as well (I happen to own a former golden flake P30 with a naturally aspirated 6.5l from the mid 90s). 98.95.90.244 (talk) 19:27, 28 April 2010 (UTC)

Other DD V8's
Would it be prudent to add other Detroit V8s that did not belong to a specific series such as the 8.2 "fuel pincher"? — Preceding unsigned comment added by 69.117.254.98 (talk) 11:56, 25 July 2013 (UTC)

The 6.2 Liter is NOT a Detroit Diesel
The 6.2 Liter GM Diesel is NOT a Detroit Diesel engine. While Detroit was in on the original design concept, they do not claim this engine, nor do they offer any parts availability. There fore this entire page is wrong, starting with the title. I would like to see someone find a claim to a 6.2 Liter Diesel being a Detroit Diesel coming from a Detroit site.

 * Detroit Diesel Engine Division was a subsidiary of General Motors at the time; Detroit did the full design, as well as an initial (test?) production at their Detroit Diesel Engines Foundry Plant in Bay City in Michigan - there are 6.2s in the wild dated from 1980 to 1982 with the Detroit stamp on the block. Afterwards the production was moved to GMs Flint plant. It's a GM engine, designed and initially built by the GM subsidiary Detroit Diesel.
 * Afaik Detroit was long gone and not in any way involved with the 6.5, but at the same time it's essentially a bored 6.2 which doesn't really take away it's origins as a DDED design.
 * The later Optimizer update and P400 redesign have a much weaker claim to any Detroit heritage IMHO. Norgeek (talk) 10:09, 19 January 2024 (UTC)

The header is wrong, Detroit Diesel did not build the 6.2 or 6.2, they were built by GM DA427CAR (talk) 18:21, 22 April 2021 (UTC)

Marine Diesel
If it’s also a marine engine, as per the category, ought there not to be at least a passing mention of its application in floaty things? Mr Larrington (talk) 22:12, 19 May 2022 (UTC)

P400 vs Optimizer 6500
They're two different engines, both made by GEP/AMG. The 6500 is an improved version of the GM 6.5, the P400 is a redesigned version. They're still both in production as far as I know, but the P400 is now offered exclusively for the HMMWVs employed by the US military forces as far as I know.
