My impala is running now, but I was told that I have a crack in my block. So That's why I wanted to just start fresh. I know my car is big and will take alot of power to get it where I want it. But I don't have the money to go out and purchase a a powerful crate motor. That's why I buying a bare block so I can do it sections at a time. The 327 bare block I bought, I already sold it and now i have a 427 bare block on the way from summit I'm pretty sure I will have it professionally for me.
