GMC 6.0L Hauls plenty

I still say the 6.0 came directly from the Chevrolet V-8's of the fifties. No? I think it is great that an engine that still uses pushrods can compete at all.

The only thing that is the same is they have eight cylinders, cam and pushrods. Totally different heads, block intake, distributor less. the list goes on and on. The 6.0 is based off the LS1 which was introduced in 1997 in the C5 Corvette. The First 6.0 was an all cast iron motor(heads and block) Tons of improvements have been made since 1999.
Until Ford introduced the Supercharged Cobra and 3 valve Mod motors No N/A powered 4.6/5.4 mod motor could run with an LS based motor for size, power and MPG.
That "pushrod motor" has less moving parts, more torque through that power band and takes up less space then it's over head cam counter parts.
At any rate, Mine does fine lugging around my 7600lbsish trailer and 6000lbs loaded truck. It is leaps and bounds above the 1989 454 truck that I had.
