You wont find much that says "GM has not produced a Chev engine since xxxx. All the engines produced since xxxx are GM Powertrain". You need to read between the lines and look at the dates that GM consolidated its operations. Wiki is a good source as well but wiki being wiki its hard to back up the data as being gospel.
At the end of the day you will have a hard time trying to convince people anyway. If they have made up their mind they wont listen to reason and you will just end up flogging a dead horse. Having knowledge is one thing, trying to change the world with that knowledge is another thing entirely :-)
your plucking at straws
gm may be the enity of it all but it's still a division of chev....in a sense
who really cares anyway?
it's a v8 and we get to enjoy it
are you also saying any 304 produced after 1988 is not a holden motor?
as they did the same thing back in the day
GM is not a division of chevrolet at all. Chevrolet is a brand of General Motors, as is Holden, Buick, Pontiac, Vauxhall and a host of other brands. The V8 engines fitted to these cars are not brand specific, they are all GM Powertrain products. You can not buy a brand new Chev engine, nor can you buy a brand new Pontiac engine etc. You can however buy a brand new GM Powertrain engine which is fitted to these brands.
In regards to the Holden 304. The last locally produced V8 rolled off the production line in June 1999. So no, I am not saying that the 304 produced after 1988 is not a Holden engine at all as it most certainly is a Holden engine.
"The Holden V8 is an overhead valve (OHV) V8 engine which was produced by Holden in Australia between 1969 and 2000. The engine was used initially in the Kingswood and Monaro model ranges; it was later utilised in the Torana and Commodore ranges. The final iteration, the HEC 5000i, was phased out in the VT I Commodore in 1999, replaced by the imported American GM-Powertrain Gen III V8. The engine continued briefly in the VS III Commodore utility which continued to be sold alongside the VT model until the VT/X-based Holden Ute referred to as the VU series debuted in 2000."
Like I said earlier, having knowledge is one thing, trying to change the world with that knowledge is another (as demonstrated above).
