you joking but I did consider that a few times. Just can’t deal with how crappy a 6 sounds. But yea, that would be neat.
I’ll tell you guys this. I’m thinking maybe the 5.7 is a gas hog. I had a 99 Silverado extra cab 5.3 with a Texas speed 212/218 high lift and that heavy thing got 19-20mpg. With heavy *** 20” wheels and super heavy tires. My 2019 Silverado 5.3 gets really good mileage stock. I know it’s newer tech and direct injection. But still gets amazing mileage. Maybe this 5.3 will do better. I’m just getting stir crazy because it’s not done yet.

thanks. Ima see how it does with a bigger stall. Leave that cam. Don’t like it, I’ll swap it.

The reason why different vehicles get different mileage is weight, aero and gearing. The Silverado has bad aero, but the weight is probably equal so my guess is that it's geared better for the driving you do. What gears are you running now?

weight is equal to what? Gto is 3800lbs stock. Silverado is MOST DEFINITELY a good bit heavier.
silverado has 3.73 gears, 30” tall tires. Gto has 3.46 gears, 26” tall tires.

my preference is an auto. And if it’s such a fail, why are the new ones coming with an auto now? Stupid gm, they didn’t get your memo. Lol.

All kidding aside, ever think of going G8 or SS? You could do to that what you've done to the GTO. And your kids wouldn't have to wait for the seat to go forward.
