	Third Generation GM small block V8 - Camaro Wiki
		The LS1 engine is first member of the third generation of the GM small block V8 engine.
		All LS1 engines built for 2001 and later used the revised LS6 intake manifold and a different camshaft, increasing horsepower ratings by 5 hp and 5 lb-ft across the board (350hp in the Corvette, 310 in the Z28/Trans Am, and 325 in the SS/WS6).
		The LS platform was further extended by a fourth generation of engines, including the LS2, LS7, LS3, and LS9.

	NationMaster - Encyclopedia: GM LS engine
		During GM's reliability testing of this engine in its prototype phase, the LS7 was remarked to have been repeatedly 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.
		This engine was modified with a 3.5 in (88.9 mm) bore for the 1936-1948 346 inÂ³ (5.7 L) engine.
		For 1964 the engine was bored to 4.13 in (104.9 mm) and stroked to 4.00 (101.6 mm), raising displacement to 429 inÂ³ (7.0 L).

		This engine was modified with a 3.5 in (88.9 mm) bore for the 1936-1948 346 inÂ³ (5.7 L) engine.
		For 1964 the engine was bored to 4.13 in (104.9 mm) and stroked to 4.00 (101.6 mm), raising displacement to 429 inÂ³ (7.0 L).
		Although the modernized engine was compact and light for its displacement and output, 429 inÂ³ represented the limit of the original architecture's expansion, and it had been surpassed by Chrysler's 440 and Lincoln's 462.

	Buick V8 engine information - Search.com (Site not responding. Last check: )
		Originally intended for 180 in³ (2.9 L) displacement, Buick was designated by GM as the engine design leader, and decided to begin with a larger, 215 in³ (3.5 L) size, which was deemed ideal for the new "senior compact cars" introduced for the 1961 model year.
		Although dropped by GM in 1963, in January 1965 the tooling for the aluminum engine was sold to Britain's Rover Group to become the Rover V8 engine, which would remain in use for more than 35 years.
		In the mid-1970s, GM was using powerplants sourced from various GM divisions where the Buick V8 was considered a factory option with the Buick 350 as the sole survivor, or in the worst case, for Buick vehicles where the 400/430/455 big blocks were phased out because of fuel economy/emission requirements.

		The 327 in³ (5.4 L) V8, introduced in 1962, was bored and stroked to 4 in (102 mm) by 3.25 in.
		The 5.0 variant of the 4.3 was bored and stroked to 5.0 L (305 in³) with a 3.74 in (95 mm) bore and 3.48 in (88.4 mm) stroke.
		The engine's physical dimensions (oversquare 4.00 in bore and 3.48 in stroke, 102 mm by 88 mm) are nearly identical to the 400 hp (300 kW) LS2 engine of today, but of course much has changed.

	Chevrolet Big-Block engine at AllExperts
		This engine was replaced by the 409 as Chevrolet's top engine in 1961 and went out of production for cars at the end of that year.
		The big-block was expanded again for 1970 to 454 inÂ³ (7.4 L) with a 4.251 in (108 mm) bore and 4 in (102 mm) stroke.
		GM continued to use the 7.4 L 454 in their truck line, introducing a new Vortec 7400 version in 1996.

	A Beginner's Look at Swapping an LS-Series Engine into a Classic Truck
		The LS series of engines from GM, commonly referred to as Gen III engines, began production in 1997 with the aluminum-block Corvette 5.7- liter LSI (its higher performance sister is the IB6) with similar versions in the F-bodies (Camaro and Firebirds).
		Of course, LS1 engines are available as crates from GM Performance parts, and there are companies like Street and Performance that eliminate the running-around part of the equation by keeping a good stock of low-mileage engines that can be equipped to suit your needs.
		Even though the LS engines sit at a zero angle in the Vettes, the four degrees is recommended to help with your pinion angle.

		Although the LS series shares the bore center dimension and most--but not all--of the traditional Chevrolet bellhousing bolt pattern, it should not be considered a "development" or "extension" of the Chevrolet Small Block engine.
		GM themselves are very careful to NOT use the name "Chevrolet" in the description of the LS series engines, prefering to call them "Small block" or "new generation small block" engines without the word "Chevrolet" in front--although they clearly want to promote the misperception that it is an outgrowth--a new generation--of the Chevrolet design.
		Engine bore was 3.875 in (98.4 mm) with a 3.25 stroke.

	Pushrod - WOI Encyclopedia Italia
		The cause is historical: The OHV engine came first while OHC engines were developed as more expensive high-performance engines and have largely replaced the pushrod design, particularly in countries where cars are taxed based on engine displacement.
		Compare this to modern OHC engines that rev to 7,000 rpm in the case of ordinary engines, to 9,000 rpm in the case of high-performance engines like the one used in the Honda S2000, and even past 10,000 rpm in specialty engines.
		These engines combined much of the performance of the overhead camshaft with the ease of service of the pushrod, but were more expensive to manufacture than either competing design.

		GM settled the lawsuit, then promptly declared that all GM engines were "Corporate" property, and therefore they could install any engine in any division's cars without buyer recourse.
		GM loves and encourages the mis-perception that the LS is just an outgrowth of what came before, because what came before had a stellar reputation and customer loyalty, whereas the new engine is a clean-sheet design sharing NOTHING except bore center measurements (4.40") and most but not all of the bellhousing bolt pattern.
		Oldsmobile engines have rather poor combustion chambers and are prone to "ping" and detonation.

	ATL Fuel Cell - Overview - Vortec 5700 Race Engine — Circle Track
		The sanctioning body had committed the sin of breaking away from the racing norm to spec in GM’s Vortec 5700 powerplant—an engine that is fuel-injected, nearly bone-stock and (gasp!) computer-controlled.
		Because the engine is injected instead of carbureted, the entire fuel delivery system had to be reworked—especially the fuel cell.
		Because fuel-injected engines are going to be the standard in racing’s future, Circle Track decided to take a look at the entirely new fuel cell Aero Tec Laboratories (ATL), one of the most respected names in the fuel containment business, developed for the ASA.

		The LS also benefits from a 9.5:1 compression ratio and more lift from Chevy's hydraulic roller camshaft (0.268-inch lift on the intake and 0.274 on the exhaust lobes).
		The engine is built around a cast-iron block with aluminum heads, and fuel is fed through a sequential multi-port electronic fuel-injection system.
		GM made minimal changes in the configuration of the engines, so things are pretty much the same on those years of trucks.

	Using A Carburetor on an LS1 Engine
		The Third-Gen engine design also employed a distributor-less ignition system using sensors on the crankshaft and camshaft to determine top dead center in order to fire one of eight individual coil packs in the proper sequence.
		These vehicles used almost identical engines with the following exceptions: the engine blocks are cast-iron and use a different oil pan, the intake valves in the cylinder heads are smaller, a taller intake manifold raises the runners, and a dual fuel-line return system was used.
		Today, GM offers a complete, injected LS1 in crate engine form (part number 25534322), but since they've been used since 1997, they're becoming much easier to find in boneyards and swap meets, which would be a lot more affordable for those of us with little interest in its fuel injection and electronics.

		An engine specialist from a professional race team provided the technical backup for the author, and I believe the consensus was that the Caddy engine was superior because of the 2-peice block.
		Relating these engines to the original BOSS 302 is debatable - the heads are totally unrelated (and thats a good thing) and the rest of the engine is simply a small evolution from existing crate engines.
		The truck/Mustang engine is thought to debut in the 2008 F-150 and probably in a Mustang after that (and whether the restyled and repowered Mustang debuts for 2009 or 2010 is still an open question).

		The 2001 LS was named LS 430 for the obvious reason that the DOHC, 32-valve VVT-i V8 engine grew from 4.0 to 4.3 liters in displacement (horsepower remained at 290 though torque went up to 320 lb-ft).
		In a later full test of the 2001 LS 430, we found the $61,171 car jetting from zero to 60 mph in just 6.4 seconds and completing the quarter-mile in 14.8 seconds at 96.1 mph while leaving the shifting of the five-speed automatic transmission up to the computers instead of the driver.
