By 2008 the tooling for World Products’ cast iron engine block for the Small-block Chevrolet needed replacing. It had served them well since the 1990s, but the cost of re-tooling was substantial: $570,000. Since they were obliged to invest so heavily in new tooling, they determined to incorporate every advantage learned during twenty five years of casting engine blocks. And they did.
