4l60e Or 4l80e
If you would like to discuss your options feel free to give me a call.

Have either of them build you a 4L80e.
Spend the extra money you will not regret it I promise, because, if you are at 425rwhp and want 550rwhp, when you get to that point you will want even more. It is an addiction that is as addicting and expensive as crack, but, it is more fun. You will push the 4L60e to its limits at some point and a 4L80e with a few simple upgrades will give you the peace of mind to go as far as your wallet will take you.
