We've seen lots of stories of people splitting pushrod blocks quite literally down the middle because they've exceeded the power capabilities of the block. For a stock 302 block, it was around 600 HP. Anything more than that, and you're on thin ice. We've had these arguments with modular blocks too. Because there are many different production versions of the same block in both iron and aluminum, the debate is often about which block is strongest amongst the group. Sometimes people will say a Teksid block is "good for over a thousand HP." Some people say an iron 03 Cobra block is good for twice that. And some people say an iron boss block will handle even more power. (these are just random exaggerated guesses... I don't know what the actual power limits of these blocks are). With that being said, we have very little facts in which to base these arguments. It's mostly based on what racers claim to have accomplished. And even that is based on a tiny sample size. So, I'd like to know. Who's split a modular block? Who's damaged or destroyed one because it simply wasn't strong enough to handle the power that was created? Damage caused by broken rods peeking through, melted pistons, or warpage due to overheating doesn't count. I've destroyed a Teksid block. But it certainly wasn't because the engine was making enough power to tear itself apart. Instead, my block died while it was idling. The shop that installed it didn't burp the coolant properly and overheated it while letting it idle in the shop before strapping it to the dyno. What's the most power anyone's made on a modular block? Who's actually destroyed one due to power? What's the point of reliable, repeatable failure? 1000 HP? 2000 HP? Is it higher than the strongest available internals are capable of, making it a non-issue? I want to know once and for all. I'm willing to bet that even a lowly stock 96 GT block can withstand more power than 99% of us make on the street. A Teksid block or 03/04 iron block can withstand more power than 99.9999% of us make on the street or strip.
