Question Whats A4 mean???

Everyone on this site puts A4 as extra performance mod. Is that a kind of lt1 or what? Someone please explain it to me, if it is how do I know if I have it. Thanks.

And when you slap some twin turbos on it, it becomes A6.

well keep in mind that the m-6 is for the 6 series muffler bearings that come in the performance package of the 1994 SS camaros with the piston slap return springs and the Supercharged blower hose

I thought it was the LS1s that had the Piston Slap return springs.
It helps keep the amazing high RPM boomerang pushrods in place.
