When my 2000 Suburban was T-Boned by some dude 5 minutes from home the insurance company totaled it and sold it back to me for something like $700. I wanted it for the 6.0 and 4L80e, and sold all kinds of other parts off of it for a couple grand extra in my pocket. When Richard Holdener asked if he could trade me something for the 6.0 so he could do the 6.0 Big Bang engine I told him sure and to kiss my baby on the cheek before he gave it all to her. He did of course, and she gave him all she had before finally giving up the ghost. But the peak power isn’t the story here. Sure it made 1,482 hp and 1,330 lb ft of torque on the completely stock and original short block, including rings and bearings, but when compared to the Gen 4 6.0 Big Bang he did soon after, there are some difference that we think helped the Gen 4 live to see even more horsepower.
And that difference is actually torque. You have to see the data to see what we are talking about, and the good news is that all that data is right here. Watch the video and let us know what you think. My race engine and drag racing buddies, please look at this one and tell us what you think. It’s impressive as hell on both versions, with regards to pure power, but we like to get all CSI on stuff and see why it broke compared to something else.
Check it out.
The horsepower numbers before failure are surely epic.
I can’t help but think the hypereutectic pistons gave up the ghost under all that cylinder pressure. A rod with no piston will not live long. I was curious what the other pistons looked like. If there was any signs of detonation, ring lands cracked or broken, etc.
