Oh yeah, hate the metric system. I mean, it’s objectively better, but just does not compute for me. I think as it relates to “5.0”, it’s more about the brand, for lack of a better term, surrounding the fox body 5.0. And since that’s where I got this driveline from, it makes sense. Plus, it’s a good round number.After decades, I'm still trying to wrap my head around the metric system. I still think in cubic inches, but, what do I know. Personally, I think the 5.0 in retro looks pretty cool and anyone under 60 understands it.
