Not to be a dick to the OP but typical clickbait Jalopnik article written by someone who doesn't really know the content in the article. 53 blocks should be avoided but they aren't guaranteed junk, just don't go crazy cranking up the power. KDP is not all that hard to check, everyone who's into 12-valves knows about it. Similar story with VP44 pumps, they aren't great and have issues but if you upgrade to a high-capacity lift pump and run lubricity additive in the fuel they run for a long time. Worst case you just convert to mechanical setup like a P-pump or even VE pump. In recent years guys have figured out how to build VEs get 600+ HP.
