So now whats your cost? 3500 bucks? Conservatively probably. I could still fire 3 or more bullets compared to my motor, which admittedly was on the high side of the budget for a street/strip build.
I don't have any idea what I would put it in, but I have gotten real close several times do buying a 5.3 and putting together a turbo setup, just because how do you turn down 800+ horsepower for that cheap.
I just watched the 8s for 8 thing where a dude went 8.70s for under $8k. Im not as old as some of you guys but I am old enough to remember when 12.9 seconds was supposed to be fast. Its not really anymore. And a lot of that has been driven by how capable that late model GM powerplant is.
FWIW obviously I have a Pontiac. So its not like Im a hater here. I just think Im a realist, and I find myself defending things I don't really care about that much. As has been documented in this thread, the gen III+ stuff took the best from 70 years of pushrod motor design. The result is a better product.

Engine which will have similar power and will also need the induction system. Gonna be a pretty close wash when compared to that GM crate LS.
You can start comparing these things all day and if you do the same. Junk Yard LS, or you find a used 400/455. Machining costs will be nominal. Everything you have to buy for the pontiac, you have to buy for the LS.
Every time I've ever looked at it, it's six one way, half a dozen the other.
