GM Gen 3 vs Gen 4 LS Engines...What are the Differences?
Автокөліктер мен көлік құралдары
LS engines are hot because of their availability, affordability, and compact size. That makes them ideal for engine swaps into seemingly anything (sorry Ford guys)!
But which LS engine are you looking at--Gen 3 or Gen 4?
If you're scouring a junkyard for a potential LS swap, there are some telltale signs to discern between a Gen. III and Gen. IV LS engine. Things like front timing cover, knock sensor location, cylinder head style (cathedral ports), AFM, and other components are key clues to which engine family you're looking at. In this video we cover some of the main visual differences between the two engines. Once you've determined if you've found an LS Gen 3 or LS Gen 4 engine, you can narrow the engine down by RPO code.
Watch this video to delineate between engine families, and then check out this link to continue your LS engine identification: help.summitracing.com/app/ans...

Always great Tech from Summit Racing. But I'm planning to upgrade the LS3 in my 2017 Chevy SS (made in Australia) with either an upgraded LS style crate motor such as the 427/570 OR even go further and drop in an LT engine (wet sump) but it would help greatly if you would confirm which Çruise & Connect Chevrolet Performance package would fit and work in my SS. An LT5 with an 8 speed auto trans would be ideal but is that a viable option? If not, what package would you recommend that would be simply drop in and run? Thanks in advance. Cheers.
can I install a genIV single bolt cam on a gen III engine? Am i able to change just the cam sprocket to make it work or would I need to get Into all the reluctor wheel stuff?
The cam Bearings are different as well from the gen 3 to the gen 4s
Hey im getting ready to build an engine from scratch so i can swap it into my sierra. Doing a full restoration. Anybody have some good tips? Id like to use that 7liter block and use a deeper piston stroke along with a turbo or super charger. But drive by wire and with an 03 transmission. I know the ecu is gonna need completely reprogrammed

LS4s always trip up even hardcore LS guys. They forget GM made a FWD LS. They came with an all-aluminum construction with cathedral 243 heads. I love mine, and it's a pretty capable platform if you ditch the dog poo 4t65e trans. Great video!

Wouldve been more impressive with LT6, but what do I know. That paint job slick tho
The '02 Escalade had a throttle by wire. I know this because that's what I pulled from one to install in my '70 Skylark.

The debate is SBF, SBC, LS or an LT in the 71 Pinto Halfhatch.
@ispeakmurican4327

If you want unique, do sbf or LT, if you want inexpensive go sbc, if you want the most power for a bit more, go 6.0/6.2 LS. Yes a turbo will make good power with a 4.8/5.3 but the old adage is more cubes = more power. The only hinge is weight.

Cam sensor extension cable, Might need lingenfelter 54x to 24x box, and maybe some injector connector work. If the gen 4 has vvt and /or afm you'll want to deal with those too. Use the gen 3 oil pump (Melling 295) on the gen 4 after dod delete.

No one knows what they are doing when it's their 1st time at anything, no matter what it is. It's only after you gain that 1st try/experience is when you gain experience, because you learn from what you just did. ✌
