I'll just say, it's the "Swiss army knife" of engines...
* It's small in size
* It gives good power
* It is reliable
* It responds well to upgrades

Subliminally putting a subaru logo when talking about blown headgaskets was great. lol

The content on this channel in the last 6-12 months has just got better and better keep up the awesome work guys!

As a native Detroiter calling it a "Chev" pains me in ways that can only be described existentially.
Great base explanation of the motor.

Pushrod motors are my engine design of choice. Primitive but reliable and effective. 700k miles no problem.

I remember when i worked at holden an engineer told me the high output v6 engines were more expensive to build than the LS engines because they were were more complicated with the overhead cams but they could still sell the LS at a higher price as enthusiasts were willing spend more money on a v8.

15:10 That o-ring that seals the pickup tube to the oil pump was the cause of low oil pressure on cold mornings. Changed that instead of the pump and saved a ton of money. Got oil pressure like new on a 290, 000 mile engine now.

Two things: Crank-driven oil pump, and Cross-bolted mains in a long block skirt. Those two things alone make the LS the strongest engine out there, and make it super-popular. Race engines use main girdle kits for the same reason - stiffening the block lower-end and increasing crankshaft support

Well shown... Simplicity is key to strength and reliability.

I recently got a Pontiac GTO (AKA Monaro) with the LS1 and I'm happy to join the LS club!

[BlindBatG]

Compact design, strong bottom end and high flow heads. Being cheap and easy to find is the icing on the cake.

2012 2SS/RS Camaro. Downtown Atlanta rush hour traffic, doing 65, drop the 6 speed one, punch throttle, change lanes, hit 90 really quick, feeling like an automotive god.

As a non-mechanic, this video is amazing! Thankyou for providing it...

[Renny]

136, 000 miles- 220, 000 k's. Drives like new -like the last one I had -still has the same grunt it had when brand new. Love this engine.

[bigboy]

I’ve got a LS (L77) patrol I love it brings me joy every time I drive it

You will notice that the timing cover has no locating dowels to the block, on initial assembly, it is important to fit the timing cover with seal installed without tightening down the bolts completely, then fit the balancer, then complete tightening down the timing cover bolts, this ensures the timing cover is centred to the balance and minimises the chances of oil leaks.

Fantastic video Scotty! The content development on this channel has been unbelievable, and I truly hope it continues. Thanks Scotty and Haltech.

[CScottsdale]

This is THE BEST introduction to the LS engine I have ever seen. Very well done.

I'm fortunate enough to own a LS7. It's a real gem of an engine. And now, GM dropped the price, at least here in the US, for a long block crate engine, from about $17, 500 to about $10K-12K. Hot Rod magazine bought one for a project. Broke it in then did the same SAE ISO witness certification correction the engine was rated with. About 520-525 bhp and about 490 lb-ft torque. And it has a dry weight of only about 438 lbs. It's an amazing piece of power plant.

1. Price.
2. The (available) heads... 360+CFM flow, out of the box (LS7 CNC ported)
3. 55mm cam gallery
4. 6 bolt mains
5. Gaskets (they don't leak like a SBC/BBC.)
