Slated for the 2014 Silverado and Sierra line of trucks, GM has released specifications on three news engines from the "EcoTec3" family. A base 4.3-liter V-6 (dubbed the LV3), a 5.3-liter V-8 (the L83), and a 6.2-liter V-8 (L86) that looks awfully similar to the 2014 LT1 set to power the C7 Corvette.

6.2-liter L86 - AFM, VVT, DI

5.3-liter L83 - AFM, VVT, DI

4.3-liter LV3 - AFM, VVT, DI

I want to see the ratings! No more low compression motors and no more 4.8.

i like the intake manifold covers

 

[Lord Tin Foilhat]

ya they look cheap

 

[6literEat'r]

that lil 4.3 looks to be a stout lil fucker...

not sure how these engine will like boost with their high compression..
will take a lil more work to make it "safe"

 

[6literEat'r]

not gonna lie, i kinda like the coilpack covers, but that intake mani cover is hideous

 

[Yaj Yak]

direct injection is neat.


they will be okay with boost.

low boost maybe..doubt theyll handle what the lq4 handles

 

[Yaj Yak]

cuz it won't need to.

5 psi on a direct injection higher compression motor is more fun in most applications than 15 on a low one.

 

[Yaj Yak]

i bet they don't have piston slap like teh lq4 and 5.3 do

 

[6literEat'r]

lol that just means theyre "loose" and free'er spinnning...lol

They have to do something. Ram and Ford both offer 300 horsepower plus as standard now.
