Gm Performance Parts 5.3l Crate Engine

[MaverickZ71]

Found this while browsing the GMPP catalog. A 327 cubic inch version of our factory 325 c.i.d. motors, with better pistons and a slightly hotter cam. AND NO AFM! Interesting! Wish the General would start installing these at the factories! (price isn't bad, either!)

A souped up 5.3 that is ready and willing to deliver

Continuing the tradition of great small-block V-8 engines, the 5.3L LS engine has been one of the most popular we've ever built. It's been installed in millions of GM-built pickups, work trucks, vans, and SUVs. But, leave it to the GM Performance Parts engineers to go one step further and upgrade the 5.3L LS. The result is a High Output 5.3 that is just as capable serving as a workhorse it's just a little bit more fun.

 

We started with the base engine the tough, proven, and dependable 5.3L engine. It's the same long-lived production engine that you'll find in our award winning full-sized truck and SUV line. The stock 5.3 offers a dependable 295 horse-power and 325 lb.-ft. of torque from the 96mm bore by 92mm stroke engine design.

 

What makes our LS327/327 crate engine so special is that our engineers added a GM Performance Parts performance cam and Grafal-coated pistons. With these simple upgrades, the LS327/327 kicks out 327 horsepower and 347 lb.-ft. of torque. And, just like the stock 5.3, the LS327/327 is capable of thousands of miles of dependable service while returning outstanding fuel mileage, thanks to the superior design of the LS Family of engines.

 

Try the LS327/327 crate engine by GM Performance Parts. Your truck will thank you!

Not a bad thought if anything ever happened to mine. I remain amazed at the mileage and performance of my 5.3 and it's got 137k on it.

The stock 5.3 in the GMT900 puts out 338 ft-lbs of torque (flywheel), so they're comparing to the Gen-3 version. A decent tune can get another 10 to 20 ft/lbs to the wheels, meaning that the flywheel is seeing ~15% more than that (12+ ft/lbs). So, a conservatively tuned Gen-IV 5.3 will put ~350+ ft/lbs @ the flywheel.
