L8T engine!

[@AbstractDreamz]

FYI GM bracket part 12652395 allows use of the dual alternators. Second, you can swap the 170 amp alternator for one from the same year diesel and get 220 amp. Normally GM used the 220 and 170 in the dual alternator setup but I am going to do dual 220 amp alternators in my 72 K5. Unfortunately laid off and cannot finish just yet. You can also check out the power steering pump from an express van and use a remote reservoir. My 21 Silverado motor came with an express van pump. Will require some rework but it is much smaller.

Great info

Nice choice. I wanted to see how one of those would do in our trucks.

At 4:42 Have you seen the cam that is coming in the GM crate L8P motor? P/N 12736191 Just putting that seed in your head, it is a factory cam in a factory crate motor that is the same as the L8T. Quote from motortrend- The L8T crate engine is listed at 401 horsepower at 5,200 rpm and a whopping 464 lb-ft of torque at 4,000 rpm. So, how much power does a bigger cam and a few valvetrain tweaks bring to the party? How about 122 hp and 79 lb-ft of torque! Yep, the new hotter-cammed L8P puts out 523 hp at 5,800 rpm and a whopping 543 lb-ft of twist at 4,600 rpm!

So a cam swap is deceiving. Yes it gives more mid and top end power but does nothing below 3000 rpm which Is what I drive at 99 percent of the time. This engine is to test how it does pulling and performing for a true daily driver. I am all for a cam swap in a weekend warrior but I decided against it on my build. Even though it would be so easy to do...

AWESOME VIDEO!!! Will the LT2 cover fit on this block?

[@danhodges2413]

So setting these up with a 10l90 is no issue?

[@JohnStright]

Does that AC compressor fit the GMT400 OBS trucks without cutting anything? Can you run the 88-98 factory R4 compressor on these motors?

[@jaxjax5322]

What year of truck did it came out?

[@tarodrickharper1914]

I'm looking forward to this swap because I want to swap the same motor into my 1987 R10. Are you keeping the mechanical fan? ICT Billet Motor mount adapters? Blackheart exhaust headers?

[@curtistate2201]

Tejas Steelworks trans and Engine mounts. See Scotty Baccus for mounts in your squares.

[@curtistate2201]

Currently running Speed engineering shorty headers cause I had them on the shelf and Dual spal fans mounted to Tejas fan shroud on a CU730 454 stock radiator

[@tarodrickharper1914]

Thanks for the information. Have you done an L8T swap before?

[@docker1689]

Get the l8p

[@bikerbrego]

How hard is it to swap in place of the Lq4 in a Hummer 05 ?

[@Rubiflake]

Looks like a good choice. That should push that two door down the road with authority.

[@kennethgray1743]

ANOTHER FACT FILLED VIDEO. Do you suggest this block as a Boost Candidate?

[@AbstractDreamz]

There is extensive info online showing that this motor is extremely capable of handling boost. I think Scoggins Dickey has a 2000 hp article and video going around. It is a big ole iron block and excites me!! I cannot wait to get mine installed!

[@kennethgray3794]

Thanks for the reply. I’m heavily invested in 2017 LT1 so I must complete I’m mission at hand.

[@SergioRodriguez-mc4cp]

Hi, I want to put the engine L8T but my jeep is manual transmission is parts available for the clutch bell housing
