anyone seen this
 

Interesting how he fit LS3 heads on a "5.3"...

I read that it's a 6.0 with a 4.8 crank, that's why it says "5.3".

Good to see someone finally did this.

I bet that thing wraps up fast. I didn't see what turbo they used.?

Isn't this pretty much how the LSX327 engines are speced? Big bore short stroke.

It's a PT8847.

That thing is singing! Sounds amazing.

They need a set of twins on it. That turbo is done lol
