Chevy 5.3L Specs????

Buddy has a stock 2000 5.3L silverado truck that runs pretty good( cant outrun my 86 silverado though). I was just wondering what where the engine specs, tranny, gear ratio, cam, heads( think vortec) etc etc where these model years and are they superior to the 87-98 years. JUST CURIOUS

hi there

well youll have to get the RPO codes off the truck for the axle ratio as there were more than one

and more than one 5.3L engine possibly.
there will be an RPO code for that as well.

axle RPO codes are G codes

engine RPO codes were L codes

http://en.wikipedia.org/wiki/Chevrolet_Silverado is a good start

superior is just a relative term and is usually opinionated. anything is superior if you believe it is, in your own mind. all engines have their own problems, and also their own superiorities.


also remove the h from where as it makes your posts confusing to read.


good luck!

Engine specs on a 2000 LM7 (5.3) are I believe 285hp/325ft-lbs

3.779in bore x 3.622in stroke
4L60-E Transmission probably
gears can range from 3.42's to 4.11's
stock cam is about 190/191
The heads are almost identical to LS1 heads but with smaller 61cc combustion chambers.

I personally consider the 5.3 superior to the 350 Vortec except for the 1999 5.3's. The 350 has a lower torque peak, but the LM7 has a broader torque curve and 30 more hp. As for the 87-95 years the 5.3 and the 350 Vortec both blow them out of the water. That's just my opinion tho and I am sure many guys will side with the 350 Vortec. I have a 2003 Chevy pickup with a 5.3. Only mods are exhaust, cold air, and a custom computer tune, and it runs good for what it is.

One major note about the 4.8/5.3/6.0 is that these engines do not interchange any parts with the original Small block chevy, besides the cam bearings (and maybe the roller lifters?)
