I’m sure 4.56s and a 261 ratio np208 combined with the 6.2 would climb a wall if they had the traction.
I’m weird though. If I were a blue collar guy in the 80s buying a new square, i’d probably give the 6.2 serious consideration in the hopes of tweaking it for good economy and longevity. Those are still my two main considerations for engines.
Although, if I were said guy doing what I do now, having to tow tractors fairly often...I’d probably have little choice but to go for the 454. Actually, I’d probably need a C50 to tow my John Deere 410 regularly without beating the crap out of the tow vehicle.
Then again, I’m the guy in the slow lane doing 60 with the semis by choice anyhow...
