	Chevy 350 Engine - GM Chevrolet 5.7 Liter Motor - Repair Guide & Availability
		As for their manufactured Chevy 350 engine, it was launched in the year 1968 and caused the blocks to move into crankshaft period.
		Chevy 350 engine crankshafts can have a casting number which is to be found on one of the uneven finished throws towards the front of the crank.
		When the engine rotates at approximately 3,000 rpm there is bound to be frantic and violent movement of the pistons inside the engine.

		The Vortec 4300 is a 90° V6 truck engine, replacing the Chevrolet 250 in light trucks and 200/229 90 degree V6s in passenger cars (the 200 and 229 were known as the V6-90, both were shortened versions of the Small Block Chevrolet).
		It is the smallest of the Generation III Vortec truck engines and was the replacement for the 5.0 L 5000 L30.
		The smallest member of the Generation IV Vortec engine family, it is unique in that it is the only member of that family that does not feature either variable valve timing or Active Fuel Management.

	Gm Vortec Engine Problems [Archive] - GMInsideNews Forums
		But when normal engines of that era with cast pistons had piston knocks, it was usually due to other issues (i.e., "galling" of the piston skirt) which did require disassembly and replacement of pistons or a replacement short block assembly.
		In the specific case of the GM Vortec engine family, GM has made several changes to the pistons and ring packages since the engines were new--and they still are.
		GM states that this is not a durability issue and it might not be, but it would cause me to second guess my engine's longevity.

		To keep the engine cool and as short as possible, the engine block and cylinder head uses the lost foam casting method for precision casting.
		Of the more than 800 test engines built, twenty-four Vortec 4200's were tested on the dynamometer and all of them met the 150,000-mile target.
		Five of the engines were kept on the dyno running at wide-open throttle until they hit 300,000 miles - a test of astounding durability.

	Vortec Conversion
		These engines were designed to meet the combined needs of performance, fuel economy and limited emissions, and represent the evolution in engineering from traditional carburated engines through the more advanced TBI and TPI fuel injected engines developed some 10 years earlier.
		In the simplest of terms, the Vortec is a Sequential Port Fuel Injection (SFI) engine, which utilizes a sophisticated computer system known as the "Vehicle Control Module", or VCM for short, in conjunction with numerous sensors to monitor and adjust the control of the engine.
		The engine, with NV4500 and transfer case attached, was lowered into the frame and the motor mounts were clamped into their approximate position and then adjusted by multiple measurements.

	Vortec Cylinder Heads
		GM Performance Parts' new Vortec Bow-Tie iron cylinder heads are available in small- and large-port configurations, and available either bare or fully assembled.
		Still, it was hard to beat some of the aluminum heads at their own game, until late last year, when GM Performance Parts introduced the Vortec Bow-Tie head, an all-new, iron small-block cylinder head that promises to deliver the performance of a CNC-ported alloy cylinder head at a fraction of the cost.
		Compared to previous GM small-block cylinder head designs, the Vortec Bow-Tie has all-new ports that are taller and narrower, the idea being to increase velocity while maintaining volume.

	Vortec Heads
		The Vortec heads will also require new rocker arms, unless you were already using the self-aligning-style arms, and chances are really good that your old spark plugs won’t fit either, so you’ll have to buy a new set of those, too.
		GM actually offers only one set: PN 12558060 (Scoggin-Dickey Performance Center-SDPC), so you’d think selecting the proper heads would be quite easy, but GM’s ready-to-run assemblies will only take a cam up to about.460 lift before you run into trouble.
		Both Fel-Pro (PN 1255) and GM (PN 12529094) make intake gaskets to fit the Vortec heads and we know for a fact that the GM gaskets are reusable because we’ve had the manifold on and off about 10 times without a leak from the same pair of gaskets.

		GM has and does take some of the P/N 12558060 heads made from either of these castings and makes alterations to them to better fit specific applications.
		Buying Vortec heads used is risky unless you know what vehicle they came out of, what part number the head is, and what modifications where made to the head to make it that part number.
		The GM valve-guide seals (0.560-inch boss) are excellent items, but when the guides are machined, the valve-stem seal boss is generally cut to 0.530, which requires aftermarket seals.

	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 carbon buildup around the intake port is due to the intake-runner design inside the Vortec head and doesn’t necessarily mean that the combustion chamber is inefficient...
		A switch from the Vortec head design to a standard-style small-block head requires that the rest of the induction system be converted as well.
		Once complete, we topped the engine off with a 750-cfm mechanical-secondary carburetor and prepared for its first pull by jetting the orifice size to 0.069 on the primary side and 0.076 on the secondary side.
