Gutless Silverado??

CHEVY AND FORD STARTED DOWN HILL SLID IN THE 90'S IF NOT EARLIER. GETTING RID OF THE ORIGINAL 5.0-5.8 L FORD/ 5.7 L CHEVY. WAS BAD IDEA. PROBLEM WAS THEY LASTED TO LONG. THE NEW FORD 5.0 IS NOT AN ORIGINAL 302. COMPLETELY DIFF. THEY JUST GRABBING FOR THE NAME SAKE TO FOOL PUBLIC.
The new “5.0” Coyote doesn’t fool anybody. That thing is a beast and may very well leave a legacy that surpasses anything the old pushrod motors did. Spend some time with them and even closed minded dinosaurs start to see the light. Stock bottom end is good for 600-700 horses just like the 5.8 and with minimal work handles 1000+ easily. Hell, Mo’s Speed Shop is swapping them in Chevys now!
The 5.3 isn’t so much a dog as those trucks are geared for fuel economy. Even with the tow package’s deeper gears they suck. Our latest suburban wouldn’t hold 80mph on the highway without constant downshifting and forget putting a load on them.
My 2017 Silverado 4x4 with 5.3L, 6L80 and 3.42s does just fine. Gets 20-22mpg at 75mph on the highway (I do lose 2mpg in temps below 40F) empty, and tow a 7k travel trailer fairly regularly and have never wanted for more power. Admittedly though, I’m at 500-1000’ ASL and not pulling mountains.
Seriously considering a TVS1900, though...been told 450whp is pretty easy and safe to get with just the blower and stock exhaust.

We have (had) four 2013 Chevrolet 1500 4x4 with the 5.3 engine. Average fuel economy is 13.5 mpg. Fairly typical for a 4x4 gasser. They were dogs for sure but the biggest problem we had was transmissions. We had to replace three out of four at 100,000 +\-miles. We sold the last one before the inevitable happened. Very little towing. We would have 500 lbs in the bed often. We are done with them.
Our '15 5.3 just pulled 295hp/336tq with only a tune and cat back. The torque curve is crazy, comes in at 2600 through 4000. This shop does a lot of the whipple/maggie screw blowers, another 150hp to the rear wheel is common.
If stock power trashes transmissions, I am assuming that you guys rebuild the transmission to deal with any extra power. If not I couldn’t see them making it long. Where the any transmission upgrades from the manufacturer compared to the 2013 models?
The 6L80 is a good transmission that can easily handle boost...but GM’s factory torque management blows.
A transmission tune is money well spent on K2xx (14-18) trucks, and best done same time as a dyno tune (local tuner is getting 310/345 at the wheels on 87 in 16-18s).

Even with the traction control off the stabilitrac still has control and will prevent you from spinning a wheel. The drive by wire system feels sluggish. Stay away from hand held generic tuners and find a good tuner in your area or mailordertuner.com
The blower kit itself is around $7k, the trans is going to go sooner or later, it should be in the budget.
If not thrashing at every stop light and going to the local test n tune every weekend, they hold up ok.
A blown 5.3L is going to put out a lot more WHP/WTQ than a 6.2L, and cost a lot more money to get there since you have to buy LTZ/SLT or Denali/High Country trim to get one (except for 2020, as 6.2L is available in RST trim).
355/383 brake for 5.3L, 420/460 brake for 6.2L, TVS1900 on a 5.3L with dyno tune can get you to 450/450 wheel.

Shit a lq9 long block and a tune would be under a grand and net 400 whp. If you add a ls6 cam and valve springs oh baby oh baby
My new work truck (new to me) is a 17 F-150 5.0 and I’m impressed. If I drive under 65 it will do 20mpg. Floor it I sport mode at it flat gets with it. I’m seriously thinking about a 5.0 short box 2wd with a loud exhaust. It’s plenty fast for fun.
