I was cruising the auction site, and noticed item #160361803393.

They claim to be basically AM General - type blocks, but machined in Canada. Certainly the photos look great. Does anyone know anything about these?

-Rob :)
 
I agree that machined is not cast. My understanding is that machined is usually preferred, meaning you start with a block of metal, then machine off what you don't need or want. I don't know exactly how engines are built, beyond what I learned in high school machine shop class.

What is the significance of the comment? Is it that blocks are cast, then machined in order to create the final block? Feel free to give us less-informed some education here.

-Rob :)
 
I believe that is the same company that used to advertise that they were cast in Canada too. I'm not saying they are bad. They might be better machined being machined in Canada.

Correct
 
i think what he was getting at is that they may be ''machined" in canada but they could be cast in another location, china for example

That is correct. I guess no one is going to the auction to actually read it!

"Compare to others: These blocks are cast and machined in Canada, by experienced, well-paid, real machinists.Other companies sell new blocks, but be careful, most are using the old casting forms, and no improvements to the metallurgy - FROM CHINA! . Booooo! There are only a handful of others in the USA offering truly IMPROVED & UPDATED castings, aside from AM General and General Motors themselves, and they are selling for considerably more than we are."

He might mean when they get them out of the container from China they then "cast" them into the bed of their pick up and take them to be machined.
That way they were cast in Canada, right? :slap:

LOL.. yep! Heres a definition!

a. To throw (something, especially something light): The angler cast the line. b. To throw with force; hurl: waves that cast driftwood far up on the shore. ...

LOL Leroy...:thumbsup:

GM still offers updated blocks?.....I thought it was all AMG?.....and AMG is allowing their castings to be copied??

Any block from gm is a gep block since 2002 or when ever gm ran out of the engines produced by them. GM sold the rights to the 6.5 blocks to am. general in 2001or 2002.
Am. general isn't allowing their blocks to be copied . there seem to be no enforcement of copyright laws any more. The chineese or whoever got ahold of a gep[am general] block and used it to make a casting mold. I wouldn't doubt that there are other engines that have been copied also.

I am not trying to be a butt head but there needs to be a distinction here. There is no real unique art to casting engines and the patent for the indirect Diesel engine is long expired. So anyone can reverse engineer and manufacture a 6.5. BUT what is wrong is trademark infringement of AM General's product recognition. GM sold the rights to the tooling (they did the engineering specs for ) and engineering knowledge. Along with some trademark rights to market back to GM customers. Legal stuff too with suppling the govt and GM with engines ( I suppose until Warranty expired on the last production vehicles and until Govt contracts ran out).

So its not illegal or unethical to sell "knock off parts" as long as they don't claim to be AM general / GEP or any affiliation with said mfg. Its a very gray area to say equivalent or same as. They should come out and say who they are and trademark or label the blocks like Motown or others who "copy" other blocks.

Does any other diesel engine get copied as much as the 6.5 ???? Or was it picked due to qty GM mfg and are failing that need replacing but people don't want to spend too much money on GEP engines in older vehicles ???
