I've seen several that spun rod bearings, had one that threw #1 through the block, saw one in the junkyard a couple years ago that threw 5 and 6 through the block. Even though I like them, I don't think they are as durable as people like to believe. In contrast, I've never seen a 273 or 318 blow up.
All those are under performers. Low power/high reliability. The slant was the same. Not designed for max power (but did great with the hyper pack) but for how long?
