Anyone tried 6.2 sbc swap?

Chevy has there new 6.2 in some of the newer muscle cars but I was wondering if these could have or have been swapped into a yj, big reason I'm wondering is cause it can switch to a 3.1l v4 to save gas.

Are you talking about the new 6.2L EcoTec3 engines? Those look very interesting. Not sure about any current versions of that engine though and don't know any YJ's with it. I have an LS3 6.2L myself getting ready to install but I'm hoping to still get 20-22 MPG with it...Not that I care .

Link to crate motor?

I think your talking about Active Fuel Management which allows it to run on half the cylinders and come on Camaro's with automatics for the L99 engine. 400hp/410tq. Most people with the AFM disable it. L99 is similar to the LS3 but detuned slightly. The manual trans camaros come with the LS3 and has no AFM. Either way, I have not seen a YJ on here with an L99 or an LS3, I think I'll be the first. You can check out you tube, i think there might be one or two on there with the LS3. there is plenty around here with a 5.3L or 6.0L, be curious to see what there milage is but not really a concern for me, My 4.0L only gets 15 MPG at best anyway.

Fab work should be the same.. the wiring how ever would be a little bit of a pain.
