99-01 Silverado are great trucks

[EVRLET]

Ummmm let’s talk about this 5.7

1999+ Silverados/Sierras didn’t come with 5.7s from the factory.

Your 2001 Silverado should have a 4.8 or 5.3, unless it’s a V6 then a 4.3. Then if you have a 1500HD, a 6.0 is what you see under the hood.

Just check the 8th digit of the vin to figure out the engine size.

For the gen III LS motors:

W = 4.3
V = 4.8
T = 5.3
U = 6.0

I meant 5.3L

5.3L was definitely the sweet spot, and outperformed both the 4.8L and the 6.0L from a power or cost per displacement perspective.

The marketing and planning teams kind of blew it on that one. They wanted to induce most people to get the 4.8L, as lower cost and better fuel economy (to help with corporate fuel economy standards).

What they failed to realize is that most truck buyers want the biggest engine they can get, regardless.

Last of the T400 chassis trucks.
My 2000 C2500 WT has a 6.5L Turbodiesel. I have to tell the parts goons it's a 1998.

You know it! As has often been said, there's no replacement for displacement.
