I cant believe the power difference.

I have no idea. I guess over 5K lbs. The tune in the truck is not dialed in yet. I am sure the truck will be faster in the 1/4 with more practice on my part and when the tune gets dialed in. I was in line to go again when the rain started. So three runs was all I could get in last night.

i ran 13.9 in fullly loaded extended cab with headers and a tune. bad weather. correced it was a 13.6
also no aftermarket for big blocks? since when? and if people started running smaller motor why did i see so many 800 plus cubic inch motors at the track couple weeks ago lol

Those are some nice times Badasschevy.
There is an aftermarket for the big blocks, just not as big as the one for the small blocks.
800 CI? Damn that is a big monster! Biggest I heard of was 572. I need to get my Super Chevy subscription started again. I think the wife's Denali needs some more power! lol
Google search came up with this article:

I am sure the market for that engine is not for the faint at heart. It would be badass in the truck though.

I knew someone would bring this up... If you suck the air in 6 liters at a time or force 6 liters of air into a 4.8 you still have more displacement right? More air means more displacement right?
I think nobody builds big blocks anymore because there is not that big of a market to support the big blocks. Big blocks are few and far between in the automotive manufacturing industry. Trucks with the big blocks were a middle ground between the 6.0 and the diesel. The torque produced was not fuel efficient at all. With that much torque, why not just spend the extra 4 grand and buy the diesel and get better gas mileage and torque

Today there are many replacments for displacements, it just depends on what kinda power you wanna make. There are 2L boosted engines making more HP than the 800ci motors linked in this thread and there are also 2.5L N/A engines making ~ 1000hp. Displacement has it's place of course, but let's not make blanket statements.

We need to get too deep but displacement has nothing directly to do with torque. The fact that big blocks have longer stroke is the big reason they have more torque. Is is indirectly related but you could have a big cube motor that doesn't make torque.
Again millions of factors come into play but the way I see the explanation:
Forced induction can nullify the advantage of displacement.
Obviously the bigger the motor whether N/A, boosted, or nitrous fed it will make more power. The bigger the base the more overall power hence the 800" motors.
Edit: As for the boost vs. displacement I would say in general it is correct because the amount of air and fuel if used fully directly relates to the power output.
