Talk:Cadillac V8 engine

"and today is the only General Motors division to retain its own V8 design." But what about the Chevy small block? RivGuySC 05:31, 30 December 2005 (UTC)
 * Technically it's a major evolutionary step from the original Chevy small block, but it's now the "corporate" V8 and can be used in other models, whereas Cadillac still uses ONLY the Cadillac V8s. However, it seems that the Buick Lucerne is breaking even this rule, since it can be had with a Northstar.--King V (talk) 20:30, 1 April 2009 (UTC)

Who said, that factory power ratings for 500 Engine has any real basis? Check out this site: www.cad500parts.com
 * Do you have evidence to say that the factory ratings are unrealistic?. In any case, it's irrelevant. This is not the place for advertising, or speculating as to what CAN be done with the engine - almost any engine these days can take advantage of modern designs/upgrades.  This is about the Cadillac V8 engine as produced from the factory.--King V (talk) 20:30, 1 April 2009 (UTC)

Why are the 425 and 368 in the "small block ohv" section on the TOC and body? Both engines' descriptions refer to their being derived from the 472 architecture. — Preceding unsigned comment added by 2603:9001:3605:CB01:1081:DC33:E8B9:BD2D (talk) 01:59, 23 December 2020 (UTC)

questions/comments on downsized ohv segment
linked thru to here from another article talking about the v8-6-4... there's some bits of unexplained jargon in there that either need to be cleaned up or linked (unfortunately I lack the knowledge to do either) - doubly so as I'm reasonably au fait with most car engineering terms, but am still stuck on them.. 1/ 'stacked like cordwood'? I'm unsure as to what this expression means, it's not exactly common english. Were they scrapped, and so piled up on top of each other, or is it more of a canadian lumber logjam situation (long line of cars), etc? 2/ not torque the headbolts ... to avoid Helicoiling the thread. OK, something like boring out the thread, or whatever? Reasonable to leave it in if it's a genuine term, but needs a link

also i'm bemused by the comment that cars with the 4.9L engine got their best performance in 1st gear (upto 45mph) - did Caddies have some quirky transmission where they typically accelerated harder in 2nd gear, or is this totally redundant seeing as almost any road vehicle, particularly a car with a powerful engine and transmission with few gears (as opposed to, say, a 12-gear truck) will perform best in 1st? btw, it's all well and good getting your 'surprisingly strong' 200hp at low-ish rpm, but if it were opened up a bit more it may have produced a lot more power at higher revs without necessarily losing that midrange punch... —Preceding unsigned comment added by 82.46.180.56 (talk) 22:09, 10 March 2008 (UTC)

"Stacked like cordwood" is a fairly common US term. It means the engines were physically stacked up -- probably because they were replaced under warranty. I don't have firsthand knowledge of that being the case with the 4100 engine, but it's not unusual to see defective parts stacked behind dealerships after a big recall.

Helicoil is a trade name for a threaded insert used to repair a threaded hole that has been stripped out. It's commonly used with spark plug and head bolt holes.

I don't know where anyone might come up with citations for all of the unattributed statements in the 4100 section. Most of them are common knowledge among people who are familiar with 1980s GM mechanicals, but I doubt they were specifically published anywhere. Old GM TSBs might be a source of citations. —Preceding unsigned comment added by 76.99.107.197 (talk) 02:43, 14 April 2008 (UTC)

Northstar section issues
First of all, there are two identical headings (and some related mangling), which seems to have been caused by the bigger issue, a large amount of information being copied from another article (GM Premium V engine). The two articles seem to have diverged slightly since the content was copied (April 2008), but they're still mostly identical. It seems to me that the best solution is to diff/merge the two sections and put the "current" version into the Premium V article, and just use a "main article" link here with the summary and preexisting subsections. If there are no better ideas (or objections), I'll try to take care of it sometime soon myself. --Fru1tbat (talk) 18:15, 5 December 2008 (UTC)
 * Ok, I've merged in what seems to be the best/current changes to both articles into the GM Premium V engine article and restored the deleted 4.6L Northstar section from before (the duplicate text had been copied over it - while this may have been intentional, duplicating almost an entire article wasn't the right solution). The restored subsection probably needs some updating, as it's in a pretty rough state. I'll leave that to an expert... --Fru1tbat (talk) 18:28, 9 December 2008 (UTC)

Monobloc
I'm fairly certain that the "Monobloc" design combined the crankcase with the cylinder block, and not the cylinder heads with the cylinder block. Perhaps someone who has experience with this term could verify my findings.--Paraballo (talk) 04:47, 15 January 2009 (UTC)

Engine Kits
The HT4100 section mentions a kit being available to swap a Chevy engine in place of the 4100 block. This is simply not true. As it stands, present day owners and collectors are still at a quandary on how to approach a longitudinal swap for something other than the 4.1 V8. Besides the fact that the transmissions were BOP patterned, no bracketry exists to support a Chevy small block even if an adapter plate were used. Additionally, the computer controls (including fuel econ and range data) would be left non-operational, hardly satisfactory to the customer.

It was not uncommon for diesel cars (which did not have the computer controls) to receive a gas Olds 307 or 350 installed under warranty as the diesel was already an Olds block.

Additionally, using brackets and mounts from late 80's RWD Deville and Fleetwood models, an Olds block could be swapped into an early 80's RWD Cad, however, these parts did not exist when the 4100 was in manufacture. —Preceding unsigned comment added by 192.43.65.245 (talk) 17:56, 25 March 2009 (UTC)

1967 429 engine
Hi, I have a 1967, Cadillac coupe de ville. Can anyone help with why it has stripped both the disy gear and cam shaft gear? It looks like a lack of oil surply to the gears! is this a commin thing to happen? Any ideas on where to get replacement parts? Your help would be much appreciated.

2009 Engine
It references a "preliminary ratings" or "preliminary numbers" on the horsepower and torque of this engine - shouldn't we have those numbers now - in 2019? — Preceding unsigned comment added by Intelligentguest (talk • contribs) 22:30, 21 February 2019 (UTC)
