2nd gen build start

whats up all, just tore down my block and found that i spun number 2 bearing and cant wait to get started on my build. while i am on here hopefully i can get some insight from the guys that have builds done and running! shooting for the 600 range but kinda read some bad news on the blocks, maybe someone could inform me on what the block needs from me???

thrown it in the scrap heap and replaced with a late model 5sfe block. They're cheap and stronger. Don't remember specifically what years you want to look for but some quick searching should pop up that info

I had one but i let it go, i wana try and build my 3s block, i heard that the walls are thin and that i shouldn't but that just makes my decision even clearer.
