What engine can I put in my 2001 Chevy Silverado 1500?

[butt0nmashR]

I'm wondering, it's a V6 with about 195 horsepower, and I'm hoping I can buy an engine somewhere, and have it be a V8 with about 350-450 horsepower. Can I do this and like what engine would work?

I would suggest getting one from Jasper Engines. They pretty much make the best, and your truck should handle a 5.7L V8 just fine. Any more specific than that I would need more specifics into what you're looking for.
