LSA/LS3 height difference

I may be swapping my LS3 to an LSA. It's in an older corvette. Does anyone know how much taller the LSA sits? I hear 3", but thought I would ask.

No difference in height. We upgraded the LSA heads on a 2010 CTSV to a stock LS3 heads. The LSA intake has a casting on one side of the port toward the bottom to promote swirl. WCCH removes them when they perform their CNC program to flow better.

I mean the top of the supercharger on the LSA compared to the top of the intake manifold on an LS3. Looks to be about 3" taller.

LOL. I'll see if I can find that spec.

Also, just remember that LSA has a 3rd belt that drives the SC in front of the AC/main drive belt.

Sorry for digging up an old thread. But I'm interested in this answer as well.

Anyone? Anyone? Bueller? Bueller?
