GM Gen V LT: Everything You Need to Know

Article: dustrunnersauto.com/gm-gen-v-lt/
As you probably know, the Gen III and Gen IV small block engines are part of the insanely popular LS engine family. We’ve discussed the LS in depth in previous videos and what makes them so popular. The Gen V small block, codename LT, has been out for quite a while now and GM uses it in a ton of different vehicles, and the LT is starting to become popular for engine swaps.

Great job explaining. However, it would be more effective if the cars were shown far less and the actual engine more. Showing a bunch of Corvettes and Cameros doesn't illustrate the engine layout or help people to see the key physical differences in the engines

[@antor.j.medrano]

Love the LT1 engine. Cant wait till Camaro SS finally implements the LT2 engine, which they will.

[@JohnSmith-hm2ow]

Im curious to see if that will ever happen. I know thats the way its been in the past but having a comaro with 500 hp at the engine would be unbelievable .🤔👍

[@antor.j.medrano]

@@JohnSmith-hm2ow you dont have to be curious bcuz it will GM has been doing since forever, NOT only that it saves on production cost.

*and if you thinking about swapping an LT GEN V to an LS then you better think twice. LT Gen 5 is way more powerful than LS, basically Gen 5 LT is an upgrade from Gen 4 LS. The only reason LS is all hype is because its cheap and old school. LT gen 5 are new and higher tier so it's more expensive to build and Tune.*

Good evening, I was wondering did you a good recommendation for a wiring harness for the Gen V Lt1 engine? Right now I’m working with a 6.2l out of a 2017 camero SS going up against a 4l80e, into a Monte Carlo Ss

[@GameOver321]

Nice job. Thanks

[@stellingbanjodude]

The trucks haven't used a power steering pump since 2013, unless it was a 2500, and then they still use the GEN IV 6.0. So the gen V has never had a p/s pump from the factory.

[@bobwilson758]

Yes , correct . Thanks -

V10 Lt would be a dream.

[@Sandy-oy2lr]

I do love my LS7. And I'd love to see a version of it in the new C8 in the Z06 option. But, Taj Jucheter in an interview said with all the new regulations, the displacement was just too big. And the N/A power gain wasn't enough. Which is why the C7Z is an updated CZR6. Rumors are the C8Z may have a flat plane crank with QOHC config. It'd be very interesting to see how they package it.

[@Dustrunnersauto]

The only thing is, a DOHC C8 motor wouldn’t even be in the LS/LT family. Are they prepared to eventually move all their performance cars in that direction?

[@Sandy-oy2lr]

@@Dustrunnersauto Well...They changed the entire form factor. In the past, I would doubt it very much. But, now, with an Engineer and fellow gear (petrol) heads running the place, who knows. It'll sure be interesting to see what's next for the C8Z...rumors abound. will they Voodoo it? Sure will be interesting to see.

L8T is iron block like you mention, but also does not include AFM/DFM

[@JROC734]

Correct me if I'm wrong but I thought that GM didn't put active or dynamic fuel management/displacement on demand (AFM/DFM/DOD) in the 6.6L L8T? Also no start/stop crap either. Not having these systems is a good thing BTW.
