hobbdebub is an unknown quantity at this point
I have a LSx (LQ4) mated to a stock TT transmission and didn't have to cut the firewall. The reason why most have to is that the T56 bellhousing is a monster.

The swap itself was actually pretty cheap when all was said and done. I ended up selling a bunch of my TT parts and almost broke even on the swap.

You can find 5.3s in almost any junkyard for peanuts. I know most will say the iron block motors are heavy but I think they are in the ball park of something like 80lbs lighter than a fully dressed VG30DEtt.
