My first rebuild

So i decided i am going to attempt my own rebuild. 727. Small block pushing around 400hp. I am starting to accumulate all my parts and ill get started tearing down in the next couple days. Why am i feeling so scared at this point? Lol. Someone tell me im not dumb for trying this. Its just a few hundred in parts rights? Haha. So i might need some help from the gurus on here. Heres a couple photos of what i found in the pan so far. The strut bars were laying in the pan. Band material is coming off in chunks. Would a stuck servo cause the band strut to just fall out like that?

I've only done it once, back in 07/08. It's not that bad especially if you have the rebuild book. Simply follow it step by step and you'll be fine
