You said you have a LB7, the first generation of Duramax. It was rated 235 HP until 2004, where they upped it to 300 HP at the crank. We have dyno'd dozens of them stock, and they make 250 HP at the wheels on the later OS.
There isn't a stock Duramax out there that makes 430 HP to the wheels either. Even the 2017+ L5P (445 HP at the crank) only makes 403 HP at the wheels.
This is why we are starting to treat you like an idiot. You are full of crap. It is one thing to not know, e.g. "I don't know what stock power is", but it is something else entirely to think you know and be totally wrong. That is where you are at right now. That is why you are being condescended to somewhat. Stop spouting BS, start asking questions that show you are learning, and you will be treated much better. Not just here, that is true everywhere in life.
OK, once again, this forum is not for us to help everyone. It is an enthusiast board where people gathered to share information and push boundaries. Sure, there are some forums designed to help everyone, but you've found one that isn't. It is a public forum because anyone could have useful information or ideas, and we do end up helping people, but IT IS NOT OUR JOB. The attitude where you (and most other new users lately) have this entitled mindset really grates on the nerves of the people who could help you, but again, DON'T HAVE TO HELP YOU. Especially when all the information is out there on the forum, just search for it.
If you don't know how one of these transmissions fails, after 3 days of us telling you to start reading, you are possibly beyond help. We've spoon fed you quite a lot of good information, and told you how to find the rest. We have told you what we recommend (build first, 6 speed later) and why. You have to make your own decision, which means learn the facts, then decide. So go learn the facts! It's free.
