Bought this as part of my upgrade to LT4 fuel components, but after looking at the on-pump part number I'm a little worried. It's not coming up in any searches on the forum or otherwise. I bought it off Amazon from AC Delco, which advertises it as a correct AC Delco LT4 pump part number (M100263) and GM part number (84244656), as seen on the box.

So what did you find out on this?

Bought the same one after talking to a dealer and them giving me this part number when looking it up for a zl1 convertible as mine is an SS convertible.

It's the correct one.

It's cool and fun the brief times I can really get on it. Traction can be an issue but not nearly as bad as people make it out to be (did have one or two times giving a little too much gas during normal driving and spun tires). I mostly drive like a grandma though.

It does have the "whipple rattle" which is considered normal in most cases. At idle and especially right before a complete stop it can sound like muffled marbles in a can off and on. Not loud but audible.
