If you don't know which transmission you are going to use then how do you know you'll need a shorter bellhousing?

If you end up buying a T-56 Magnum and a QuickTime Bellhousing then you can simply cut the bottom lip off the bell so it's even with the bottom of the transmission. There is only about a 1/2 inch lip hanging below the trans, so by trimming the lip you will essentially have a flat bottom housing. It won't be any lower than the trans.

This is a common practice with dirt oval track racecars.

That's what I've done --- just cut the lip off.


Remember that there is usually some rake to a car -- so it's higher in the middle of the car where that bell housing is...

I'm running a T56 transmission, with stock bell housing. I'm also using a Holley pan, which is fairly shallow, and about an 1/8" above my crossmember, and my bell housing bottom is just a touch ABOVE my oil pan, so if you end up having to cut your bell housing, you'll likely need a very shallow, or custom built oil pan.
The oil pan on an LS engine is a structural member, therefore the bottom two bell housing bolts go into the bottom of the oil pan, tying the drivetrain package together. The bottom of the bell housing IN MOST INSTANCES will be higher than the oil pan.
