  GM LS engine - Wikipedia, the free encyclopedia
Engines were cast from aluminum (for cars) instead of iron and had a new intake and injection technology and coil-on-plug ignition.
It is an all-aluminum 5.7 L (346 in³) pushrod engine.
During GM's reliability testing of this engine in its prototype phase, the LS7 was remarked to have been repeated tested to be 8000 rpm capable, although power was not made at that rpm level, due to the restraints of the camshaft's profile and the intake manifold ability to flow required air at that engine speed.

GM's family of LS1 overhead-valve V-8 engines can trace its roots to the fabled Chevrolet small-block V-8, yet the LS1 is much more than an offshoot from the small-block family tree.
While the production LS1 engine displaces 5.7 liters (346 cubic inches), the racing version is a brawny 7.0 liters - a displacement that stirs memories of the 427-cubic-inch big-blocks of the '60s.
The GM Racing aluminum cylinder heads are designed to meet the airflow requirements of the racing engine's increased displacement and higher operating speed.

GM has produced nearly 90 million engines based on the small-block design – and a fair number of them ended up on race tracks.
GM engineers kept the small-block V-8 forever young with a steady flow of new heavy-duty components.
All eight intake ports are angled toward the center of the engine; the runners that supply the front cylinders are a mirror image of the ports that feed the rear cylinders.

 GM LS1 Engine Carburetor Install - Tech Articles - Custom Rodder Magazine
The LS1 is based on a skirted four-bolt aluminum block with cross-bolt mains, a nodular cast-iron crankshaft, forged powdered metal connecting rods, and flat-top pistons.
Today, GM offers a complete, injected LS1 in crate engine form, but the mills are also becoming easier to find in boneyards and at swap meets, making them much more affordable for those of us with little interest in their fuel injection and electronics.
The new intake uses GM manifold gaskets, and should be installed using a specific tightening sequence, as noted in this illustration from the instructions.

GM LS1 engine in a Chevrolet Corvette C5 The LS1 was an evolution of the earlier LT small-block V8 (and is almost identical to the LT4 except for its aluminum construction).
The Vortec 4800, 5300, and 6000 are cast-iron versions of the LS1 engine with different bore and stroke dimensions.
A version of this engine is adapted for transverse front wheel drive application, the first time a small-block family engine has been used in this manner since the Oldsmobile Aurora of the late 90s, it had a 4.0L V8.

I decided to go with the LS1 because it is all aluminum (block and heads) and is lighter than my stock 911 engine and about twice the horse power.
The LS1 Corvette engine is 350 cubic inches (5.7 liter), 345 hp @ 5600 rpm, and have a torque range of 350 lb/ft. @ 4400rpm.
Most notable is that this engine is the first two-valve V8 to reach the one-net-horsepower-per-cubic-inch plateau.

All late-model GM fuel-injected engines are managed by a computer; in the LS1's case, it's the Powertrain Control Module (PCM).
The LS1 PCM relies on programmable flash memory that governs spark timing and fuel delivery based on input from a litany of sensors that give feedback on various engine functions.
After locating an engine, the first order of business is to figure out the wiring harness, the electrical lifeblood of the engine.

Mark McPhail, a GM Motorsports engineer, says that the advances in the LS1 that will be most apparent to auto enthusiasts are weight reduction and improved air flow.
Although the LS1 differs significantly from the Chevy small block, both engines share some common characteristics-- both are 90-degree V8s, employing 350 cubic inches of pushrod, two-valve power.
GM Performance Parts is adding more than 70 new part numbers to its product lineup during 1997.

 Corvette LS1 Engine Reshapes the Future
"Few people yet realize the long-term effect that the C5 LS1 engine is going to have on the performance industry," says Joe Negri, manager of IRL and Road Racing Groups for developing the C5-R racing version of the LS1.
One benefit of developing the race engines in-house using production-based parts, is that it allows GM engineers to work with aftermarket suppliers to develop performance parts for the engines.
Instead the emphasis would be on new designs that produced engines that are fuel, weight and emissions efficient, cost effective, and socially and environmentally acceptable; engines where electronics and dramatically improved cooling, oiling and sealing systems made significant contributions to increased performance.

In spite of the impressive numbers delivered by the DRM suspension and brakes, it was the power plant that seemed to attract the most attention.
It was decided that any engine offered for street use would be, at minimum, emissions legal in 49 states if not the full 50.
It meant that engines couldn’t impress with just torque and horsepower, they would also have to idle smooth, and have flawless drivability characteristics as well.

 LS1 Corvette Engine
Based on a timeless design by former Chevrolet Chief Engineer and General Manager Ed Cole, the "Gen III" 5.7 Liter V8 LS1 marks a bright new chapter in the highly respected lineage that GM small blocks have established for more than 40 years...
With this legacy in mind, GM engineers built the LS1, recognizing this as the opportunity to evolve the small block to the ultimate pushrod V8 engine for the 21st century.
With the time-proven small block V8 design to build on, the LS1 is clearly the most technologically advanced pushrod V8 engine GM has ever produced, and is definitely up to the task of powering the legendary Corvette.

This article will also touch on the Gen IV V-8 engine blocks as that engine architecture was introduced in the ’05 model year as an improved version of the Gen III V-8 design.
That is probably why many enthusiasts call their Gen III engines “LS1s” no matter what RPO was used to order the engine (there are many RPO codes for the Gen III engine, as seen in the attached chart).
In major departures, four cylinder-head bolts are used per bore versus the previous small-block’s five per cylinder, and an oil passage runs the entire length of the block to transfer oil from the gerotor oil pump driven off the front of the crank.

 MAFless Tuning - Wikipedia, the free encyclopedia
The vehicle's engine management computer then uses this information to calculate the correct amount of fuel to be delivered to the cylinders by the fuel injection system.
The genesis for MAFless tuning of the LS1 in Australia was the HSV GTS version of the Holden Commodore, which was factory fitted with a Callaway-developed C4B version of that engine running in MAFless mode.
However, tuners of the LS1 in North America tend to prefer retaining the MAF, instead overcoming intake tract restrictions by installing a MAF with a larger diameter body.
