The modern equivalent of that engine is GM’s ZZ427 crate motor. It stays true to the cast-iron block of its forefather, but runs pump-gas-friendly 10.0:1 compression, sports aluminum heads and an all-forged rotating assembly.
There’s nothing like a quick and dirty slapdash lift job with some pucks to get the lifted look. However, this won’t hold up when push comes to shove on choppy surfaces or hard slopes. You will need suspension travel as well as flexibility and rigidness at the right times. When starting your Jeep mods, hard plastic pucks won’t give you the response and dependability you need.
It’s not that we’re going in cost order here, the LS9 crate engine ranks near the top because of its insane rarity. According to GM they aren’t building any new ones, they’re just selling the leftovers from the 2009-2013 Corvette ZR1. You know, the first Corvette to ever exceed 200 miles per hour. The one that lapped the Nurburgring four seconds faster than a Nissan GT-R way back in 2009. Nevermind that this happened nearly a decade ago the 6.2-liter LS9 is still insane today.
This Bronco came with a part-time four-wheel drive system and a V-8 under the hood. You could choose from a 5.8L 351M and the 6.6L 400. A C6 automatic transmission came standard or you could pick the optional 4-speed manual. This is the last generation of the Bronco to have a solid front axle, making it great for off-roading.
The single engine option after the 2008 model year is a 3.5L V6 that delivers 266 hp and 245 lb-ft of torque. The engine is always paired to a six-speed automatic. The combo offers middle-of-the-road fuel economy of 20 mpg combined. Where the Toyota Sienna stands out among used minivans is the available all-wheel drive system. This is a great option for buyers who must contend with a lot of snow and ice.
We will never understand why this isn’t always a default option on all new vehicles capable of off-road driving. There are times when you will need slow and steady power coming from both wheels on each axle. A limited slip differential will keep some of the single side spin down but a full locker is much better in terms of 4×4 Jeep mods. Locking both wheels to spin in unison is an easier way to get out of sticky situations. When combined with the use of a properly anchored winch, there’s almost nowhere you can’t go.
Forged steel rods. Forged steel crank. Forged aluminum pistons. Aluminum heads. Mechanical roller cam. Huge valves. A 7100 rpm redline. A massive 13.1:1 compression ratio that’s well into diesel territory. It all combines to make 776 horsepower, 649 lb-ft, and a whole lot of noise from its 7.4 liters of absolute fury. I’ll let GM explain what that all means.
GM has been producing small-block and big-block engines for decades. Throw a few extra parts on one of these bad boys and you’ll be burning tires in no time. Before we talk about the best GM crate engines, let’s start by answering a few basic questions. Ooh, shiny. (source)
