I am so excited for this. I was getting 8 mpg with my 2fDepending on my skinny pedal usage, I have seen as low as 12 mpg and as high as 16.
My 62 is running a 5.3 and 4L60 from a 2003 Tahoe. 4.10 diffs, front and rear bumpers, 35’s

That’s a tune up problem, and not normal for the 2F. I always got 15mpg on the highway and 12mpg around town on a stock 2F.
see...thats 3/4s my issue...i live at 9500' I cant leave my driveway without an "incline"Im at 12-16 highway depending on the incline with my 2F. City is always 12.

Im also thinkin a NEW, outta the crate LS3 will perform better than a used 2003 Tahoe motor...but, maybe im wrong
Man, dont sell yourself short! My LS swap is the first motor swap ive ever done and its actually not as bad as people make it out to be on the internet. Next time if you have the time you should give it a stab! Always pretty fun to push your limits a little bit. Thankfully due to covid i have a ton of time, which was really my main reason i wasnt going to do it myself in the first place. Im over here in memphis but ride mtb out in nashville all the time. Ive got another buddy named Isaac that lives your way with a reallynice 60 as wellYou are probably right, but it's all about $$$ and it does add up with a V8 swap. I got lucky and found a drivetrain from a local in Nashville that had engine, transmission, motor mounts, transmission mount, wiring harness, etc... for a great deal. I then used a local hot rod shop to do the install. If I did it again and money was no object I would ship my truck to one of the known cruiser swap gurus and bring a blank check.
My 5.3 has a torque cam and short headers and it blows my old 3FE out of the water, but it definitely drives now like a cop car mixed with a 60 series, LOL. I do sometimes miss the old iron, but it's also nice doing 80 on the interstate purring at 2,100 RPM.

That certainly wasn't a knock on your swap...jus a statement of fact that a NEW LS has to be more efficient than an older unit....just natural for tech to get better. I have ZERO wrenching skills, This is smthn i cldn't ever do, nor trust that it would be done right. I'm fortunate to be able to source it out.You are probably right, but it's all about $$$ and it does add up with a V8 swap.

Shooting you a pmAwesome man. My rig is done and back on the road! Put me in touch with your buddy Isaac…!
Of course an LS3 will have better performance, goes without saying, but that doesn't always translate into fuel economy. You can have an LS "built" WAY cheaper than you can buy a crate LS3 though. Get a 5.3 and bore it to a 5.7, cam appropriately, find a GOOD tuner, and you'll be super happy. I've done several LS swaps and love themsee...thats 3/4s my issue...i live at 9500' I cant leave my driveway without an "incline"

A LS3 is a car engine. It has a car camshaft. So you really want a engine more ideally built for a truck or SUV. There is a truck version of the 6.2. Unless you need the 6.2 LS3 erod designation for emissions I would look to other LS motors such as the truck version 6.2 or the 6.0. Even the 8.1 if you want monster torque is a option. 5.3 is fine too but skip the 4.8. My opinion anyway
I have the "car intake" on my LS1, and yes it looks much cleaner. Buy a car intake and put it on a "truck" engine if thats what you like. I did it on the 6.0 I put in an S10 alsoBut the Car intake looks so much cooler!!
Ive got the truck intake on mine, but plan on running the LS6 intake. The car vs truck intakes are a trade off like you said, they increase HP at the expense of torque. My torque is already double what it was with the 2f so i dont think losing a bit will hurt much. Down the road when i do cam/heads/injectors etc i do plan on running the car intake for sureI have the "car intake" on my LS1, and yes it looks much cleaner.

I GUARANTEE you'll never know the difference in any "lost" torque.Ive got the truck intake on mine, but plan on running the LS6 intake.
