First featured in 1962, the 327 was found in everything from fuel-injected Corvettes to the very first Camaros. It was renowned for its high-rpm performance and surprising torque from a comparatively small-displacement V-8.
Today's LS327/327 crate engine delivers on the same virtues, cranking out 327 horsepower and 347 lb-ft of torque. It's a 5.3L LS power plant with the same 327-cubic inch displacement of the high-winding small blocks from the 1960s, but it is "breathed on" and updated by GMPP engineers with a hotter cam, Grafal-coated high-silicon pistons and more.
In other words, it's perfect for re-powering your truck or dropping into your classic vehicle or street rod (check with your state or local regulatory agency for emissions regulations in your area)

i would either boost the 4.8 and do supporting mods, or swap a 6.0 or 6.2. No point in going from a 4.8 to 5.3 they can make similar power when boosted

All you need is a short block, you can find em for 2-500 easily.

LOL, Dude are you really that dumb to waste your money on that? You're going to spend $3600 on a longblock with no accessories that's going to put down about 300/300 to the wheels IF YOU'RE lucky. Those numbers are flywheel numbers. Hell the new engines make close to that from the factory.
As far as the topic at hand. I would save your money and swap to the 6.0. The 5.3l is a great engine. There are a few guys almost touching 10s with them so they can certainly hold their own. However, the 4.8L isn't a horrible engine itself. It's not great, but if you plan to do the swap I would spend the extra bit and buy the 6.0.

I doubt i was going to get the 5.3 but if it was plug and play with no worries then i figured it would have been worth it if I could have talked the man down to $450 or so. Im just going to let it go, no need to spend more money into the truck lol

all the parts you put on now will work on a 6.0 when you decide to go that route
