Does the text in question contain your keyword search terms, are customers finding you by searching for those terms, and do you currently rank on the first page of Google's search results for your key terms?
If the answer to all 3 is "yes", then you will potentially drop in Google's rankings, so I'd recommend leaving the homepage as it is.
If the answer is to any of those 3 questions is "no" (or "I don't know"), then it's unlikely you'll notice a difference.
Why do you want people to land on your homepage? You need to take into account how people search the web. If I search for the title of a book and the top link on the SERP is for Amazon, I do not want that link to take me to Amazon's homepage (where I'll need to search again) - I want it to take me to the exact page where I can buy that book.
With that in mind, is the information useful to your customer? If it is, should it have it's own page, seperate from the homepage?? It really doesn't matter where on your site the customer lands as long as you have good design & it's easy to navigate. What matters is that you customer finds exactly what they're looking for as quickly as possible and knows what to do next.
Hope that helps.

Design for people. Being #1 on Gooogle is worthless if every real visitor hates your site.
The search engines don't love "tons of text", they love unique content. With each new update, Google is trying to more closely mimic how a real human searches the web. So designing for search engines rather than customers is mostly pointless.
Best regards.
