So back to the OP…… is there any mods for the single cab people have done?????

 

im looking for more creature comforts and interior as well

I added footwell lights to my crew cab. Also swapped the ugly plastic wood for nicer black plastic.

Have you noticed any increase in mpg with the cold air intake?

Eh. Maybe a little. It’s not worse. Sounds much better.

Jeez.. what did I just read...

 

I love the 2.7 actually! great MPGS out of it. (averaging 24s).. Anyway, I wish their were more mods! But all in due time...

Hey OP just wanted to let you know I recently bought the speedform throttle body control and the pulsar LT 2.7 programmer so far from what I know those 2 things and a AFE intake are the only mods you can do to the 2.7s for now reply to me if you need help finding the things I mentioned

Oh and the fact that the 2.7 makes the Silverado/Sierra handle like a sports car compared to one with the 6.2. You don’t realize how much that front end weight makes the truck a sloppy pig. 
 

(I love the 6.2 but facts are facts)

Thats true, the center of gravity with that 4 popper located aft in engine bay on my Trail Boss enables great handling, humming to the GoodYear sounds of the Duratracs....LOL   Running E15 seeing 25 mpg+ pushing a lot of air at 65 mph ( I went up 5 MPH so the Boebert supporters here don't shoot me) .

It’s called modification. I had a few lowered trucks they handled very well. It’s not a one size fits all. I can see a lowered 2 door slightly modified 4 banger being a blast to drive. 

The WT with 430 ft lbs of TQ should be awesome streeter. Kinda like a Nova of our day. Light with some thump off the line.

My 74 nova custom had 165 hp with a 4bbl and factory duals. My CRV is quicker. Of course I modified the hell out of it. Come to think of it my Avalanche is probably quicker than it was. The 4 in your truck would lay waste to that 74 nova.

70 Nova SS with 396 4 speed was not slow. 
 

Also had a ‘70 Nova 350 2 barrel w/ headers 3 speed on floor that was efficient and fast. 

 

Agreed  ‘74 Nova SB was a dog.

Its awesome in my crew cab short box.  A RCSB has to be a hoot with that 2.7HO.  I'm sure its no F150 RCSB 5.0 10 speed, but still has to be fun.

Was researching a bit and the 70 Nova fitted 396 had less TQ than the 2022 HO 2.7 Turbo!   Nova = 375HP 415 Ft lbs TQ @3600 rpm 

L3B HO = 310HP 430 ft lbs TQ @ 3000 rpm

HO L3B Peak TQ at what RPM ?

It’s amazing the improvements in HP and TQ.

besides intake, i would look for a cooler thermostat, it yields the most HP for the money and improves reliability and reduces oxidation of fragile plastics under the hood. 

premium fuel or e85 would also mix well i bet

Poki in general I am with you on that but the 3 valve electronic water pump/thermostatic system is computer controlled and critical to idealizing hot temps on lower end of the L3B and super cooling the top end. 

 

It's really odd but effective. Why they can get 87 octane at sea level to work in this turbo boosted engine and survive.  

 

What we read as ~210 F on our coolant gauge is probably NOT what the engine is really seeing in critical areas. I say probably because  my scanner is old like me and will not give me all the inputs from the newer MIL/ECM on my 2022 LTD.  

 

As an example I have never detected and exhaust pipe outlet on a truck or car this hot except headers off a sprint car!  It literally is moving heat out the exhaust by design at rates and temps higher than anything I have tested in years.  Certainly not stock vehicles.  I will have to IR test the tail pipe but man its hot.  

 

BTW using E15 in the unit the tail pipe literally has no soot detectable to finger test.
