Default LT1 air intake diameter

I've mistakenly won an air intake for an LT1 on eBay - looks cool but I've got an LS1. Is there a practical way of making it fit? What diameter tube should fit in the LT1 intake?

Short answer: no.

Long Answer: Might be possible if you had a 90 degree elbow that fit your TB and the intake

Perhaps I should have been a little more specific. The intake I have won is a 90 degree bent aluminium tube (the same diameter of the LT1 TB) with a cone filter at the other end.
There are no clearance issues as I am putting the engine in a kit car and can work round that. I just need to know whether the diameters of the throttle bodys are similar so I can fit the intake onto mine...

Lt1 is a 62mm oval size. LS1 is a larger circular size. There's no real similarity
