Where did you get an all aluminum 5.3? Impala SS or 2007+ Tahoe?

LS motors sound eh? They sounds exactly the same as any other small block V8 I'ver heard, and they are 100x more advanced than an old SBC. I wouldn't put anything else in a car, you get so much for so little money. In fact the domestic rags have been throwing cheap ebay turbos on old worn out junkyard LS's and getting 600whp out of them with no other changes than opening up the top ring gap. That's pretty stout in my book.

And there is a TON of info on LS swaps out there, I've got a full color book in my throneroom just on LS swaps alone. It really maps out every detail of swapping them into most any chassis.
