Bellhousings 621 vs LS

[Larry S.]

I needed an 11" bellhousing so I purchased a new repro 621 bell from Keisler and they sent me a LS style bell. Other than the fifth bolt at the top of the LS housing are there any other differences? Are they interchangeable?

Thanks for the help.

My recollection is that's the only difference, so the uppermost hole becomes superfluous when used on original '621' applications.

However, if you're concerned, at all, about maintaining original configuration, then you want the bellhousing without the added hole.
