I was looking and I thought about the LS7 swap but there’s too much to worry about, I want something bigger than the LS1. If I the LS1 Is the only swap I could do then that’ll work but I want some advice on swaps and what I’d need for said swap

I don’t think you are going to find anyone here who has swapped anything other than the LS1 into a 4th Gen, and they most likely would have been replacing a V6 or an LT1. There are other ways to achieve a 427ci build (e.g LS3 427ci crate engine, making 625 HP) than starting with the very high $$$, discontinued LS7.

Cubic inches aren’t always the answer. There's a stock block 4th Gen LT1, destroked to 329ci. Making over 1,800 HP, 6.97 @ 211 MPH.
Buy a LS that 5.3l and turbo or supercharge it. 5.3's are a dime a dozen. I've seen them with trans and pc for less than $1000.
Get a LY6 out of a Silverado. Its a 6.0 that replaced the LQ9. L92 (07-14 Escalade) are pretty cheap they are 6.2 liters. If you are on a budget get a 5.3
