Is the L83 head gasket factory or OEM?
1) The L83 Head Gasket is the factory OEM replacement gasket for your L83 engine (.052″ thickness). These are good for most NA head & cam builds that want to maintain stock compression.
Is the 366 cylinder bore smaller than the gasket?
Tall deck engines are no less likely to incur headgasket failure due to this spacing than a standard engine. In the photo can be seen how much smaller the 366 cylinder bore is than the gasket which sits on it (and yes, this is the first disassembly of a factory engine).
Which is the best valve spring for a L83 camshaft?
We designed this camshaft for use in trucks with minimal modifications. Requires a GPI 4* Phaser Limiter. We’ve found the Gen 5 LT1 Spring Kit to be the best performing valve spring on the market for our L83 camshafts.
Is the camshaft sprocket bolt torque to yield?
The Camshaft Sprocket Bolt is a torque to yield (one-time use) bolt. GM recommends replacing after each use. We recommend upgrading to the Fast Fish Front Timing cover as it incorporates a PTFE (Teflon) low friction lining. This is a premium quality racing seal and substantially lowers drag while maintaining oil control.
How does the timing chain work on a GM engine?
On most GM vehicles with V-8 or V-6 engines, a metal timing chain is used to connect the camshaft to the crankshaft. This causes the camshaft to move in synchronization with the crank, causing the camshaft to open and close the valves in the proper sequence and duration for the intake, power stroke and exhaust cycle.
Can a sheared timing chain guide bolt be repaired?
Fixing a sheared engine timing chain guide bolt with original equipment typically requires a labor-intensive removal procedure. This Dorman OE FIX innovation saves hours by integrating the bolt and plug for an easy repair on GM Ecotec engines. Integrated design – plug and bolt combined as one piece to easily restore functionality
