Meth or e85?
LS3 with eForce (let's not debate superchargers here), booster pump, long tube headers and LG Supercool radiator. Considering meth or e85 to lower temps and gain some additional hp. Might consider cam swap in the future.
Cost to install (i wouldn't do it myself)?
Reliability?
Availability of meth or e85?
Pain in the *** factor?
Any other opinions meth vs e85

If you have E85 stations all over your area converting to Flex fuel is a great option. The main parts are just a sensor added and the tune adjusted. But with e85 you need more fuel so if your current fuel system and injectors are not sufficient then you will be spending a few thousand to upgrade injectors and fuel system.
IMO i would add a cam and Alky kit and bump the boost up. Around the same total cost if not less and you will see big gains. Or if money is not a factor do it all and max that e force out.

Another thing to consider is what do you do with your car. Is it a daily driver, weekend warrior, do you drive it on long trips, etc.? A car running on e-85 will get less mileage than gasoline due to it taking something like 30% more fuel than gasoline. So if you do a lot of driving it will mean filling up more. If you take it on long trips the availability of e-85 might not be available, but if you are going to run a flex sensor you will be able to run 93 if you cannot find e but then your going to be down on performance. For me it was best to stick to 93 and meth, due to the availability of e in my area and how I drive my car. But like the other guys said swap the cam, put on a smaller pulley and add some meth would be my suggestion.

Both is great, if needed. If he just has a basic eforce kit on LS3, it may make 500-550rwhp. That number doesn't require either. He needs to push it up to the 650+ range, then when it becomes octane limited, can add one or both. For now unless he is making 650+, focus on the other stuff to get there.

Good advice, I think.

I guess technically you don’t but I feel like you’ve got the question backward....lol
Why wouldn’t you need both?🤔
more bald eagles 🦅!
Im running 93 and 100% meth at the moment so I’m “meth dependent” not that big of a deal since it’s not a daily or anything. When I upgrade the fuel system I’ll more than likely run E50 or so and switch to 50/50 on the meth. So that’s my reason for both, and I already have the kit on so I mine as well use it even when I get on the corn.

Actually, what I was thinking is that if you want to use the meth to lower IAT temps, and you're running E85 anyway, why not just plumb a line from the fuel line, through something like a progressive nitrous solenoid, then to the intake? It would eliminate the alky pump and give you back your windshield washer tank. Plus you wouldn't have to worry about the alky injection pump failing. Actually, it would probably also work with gasoline, come to think about it.
