I have a 400 sbc I'm about to start building. I want to build a 427 stroker but have read that it's to risky. It's a stock block. Should I stroke it out? Or just build a 406? I'm looking to have 500+ HP any suggestions would be awesome. I don't wanna spend the money on a stroker motor just to blow it up. But if there is a safe stroker application on a stock 400 block I'd love to know.
