Since this has now become a two headed thread... the answer to your direct question will eventually unfold. So hang in there... but if you are in a time crunch, PM me and we'll go over it.

If you look at a standard Chevelle motor mount, its a good 1/2+ taller than the Camaro mount that comes with the ATS kit. Chevelle guys would most likely try to use this mount anyway. That is, untill they tried running the stock A/C system..

If you look at the other mount kits out there, they all raise the engine up higher than the ATS kit. And with good reason, they all clear the centerlink but the ATS kit....

The common denominator is the trans crossmember. As long as its stock, or in the stock location/height, you're fine.

Uhm... no.

The fact of the matter is... that it is going to change the driveline angle. And secondly, I highly doubt that most will be using the stock transmission cross member with any LSx combination... as most everyone but you, has already realized this. I would even venture to say that they have also realized that using the AC in its stock configuration is going to have an issue with the frame rail. Not to mention that the related issues with the available oil pans have been discussed for the last... I dont know, say minimum of... three years or more on more forums than I care to mention. Maybe you shouldn't include yourself in the statement of "Chevelle guys would most likely"... because you have pretty much singled yourself out.

What is the factory engine angle of the Chevelle ?? What is the factory angle of the differential ?? Have you taken into consideration any suspension geometry changes ?? Have you taken into consideration any change in ride ??

All of what I just asked, has a net effect on the driveline angle. Which, in most cases, can and will induce other problems... such as U-joint issues, balance and vibration issues and tailhousing failure.

Hummmm... that is interesting. Now, which oil pan's were being used to give you the impression that they all fit and clear the linkage again ?? Did this also account for any height variance with the body mount bushings ?? And... did this account for the guy that doesnt want to hack his front cross member to make it all fit ??

Most likely not. "And with good reason" = bandaid work around to make it fit. Notice that it doesnt mean engineered or designed correctly to maintain proper alignment or doesnt effect the mass centroid axis or check for hood clearence.

Is deceptive at best, and pretty much false when it comes to A-bodies, which, other than F-bodies, is my definition of "most GM muscle cars"... What it should say, or at least have a disclaimer about, is the fact that you can't use the stock oil pan or accessories with this kit.

After all, when it says direct bolt in, that should mean you take the motor out of a donor car/truck and bolt on the ATS kit and "directly" bolt it in the car. But, as we're finding out, it doesn't.

I have no problem with the quality of what ATS includes in the kit, but their write up on the product needs an overhaul.

Maybe your interpretation of what is stated that needs to be questioned. As it clearly doesnt state the use of any donor car relate items. The oil pan is a given... and has been for years. But since you have a real need for people to spell it out for you... every combination is a little different. To include your own. So remember, not everyone follows the Jones' around here... and build's cookie cutter cars.

Maybe it's your preception, interpretation and understanding of any write up that needs an overhaul. Because at this point... you seem to be the only one having an issue with what you have. Maybe... just maybe, you... to this point, have not done all of your homework and have not selected the best parts for the direction that you feel that you should taken to accomplish your goals.

I know that everyone else that doesnt want to "hack and fit"... has.

But then again... maybe my entire reply is just like yours. Im splitting hairs about something that I could read into a thousand different ways and that I might not have completely researched... but am expecting a miracle.
