Would the LT2 intake be overkill or will it be a good upgrade to go along with the E85? Can't do headers so I think that's about all I can do with a good tune to get some added hp. Also, do I need to get a bigger throttle body to attach to the intake? The LT5 95 mm throttle body to be exact?
Thank you for the input!

You can supercharge the LT1 without upgrading the internals. You just need to address a few details.

1) requires upgrading the fuel system to support ethanol.

2) requires proper crank case ventilation.

3) colder spark plug(NGK 7 or Brisk rr14)

I have had a Whipple 2.9 @ 10psi on my SS that retains the stock long block since 2019. I addressed these 3 things above which has been key components to the engine's longevity.

There are other supercharger options that you might consider for less money. The LT4 supercharger is one option. ECS centrifugal system is another.

It's kinda' too bad much development hasn't happened yet. There's been, what seems like a pretty focused development for the 2650s, moreso, and maybe that's because they came out in around 2019. I got mine about this time 2020, and I don't think the 3.0s came out until, what - 2023 or so? I think Josh' was about the first, here?... Regardless - I've seen a few videos of max' effort 2650s from a few shops and see A LOT of 1000 HP builds out there. There's a sheet-tonne of 3.0s getting there EASY on Coyotes, so the airflow is there - no doubt. It's just a shame.

It sucks you have to do the cutting you do for the Whipples, but if that doesn't matter to you, no biggie. SUPER-BIG-BRICKS in those babies!
