I know there was a version that got down to 230 hp. But even if this image isn’t perfectly accurate, it’s still pretty damn funny. There is an entire era of large-ass engines that are choked to hell and back so the power outputs are far less than what someone might expect.

Reminds me of a guy who had a 454 built for a 1970’s C30 by a local drag racer. Even running on straight LPG (propane) which restricts the carburetion it would spin the dual wheels – they played with the mixture and managed to nearly double the mileage, which he was after instead of outright horsepower
Chevy made a tall deck version of the big block for school busses and medium duty trucks. The 366 cid versions made even less horsepower than in the meme above–about 180 net.
But did fuel consumption and emissions get down to decent levels? The way I remember these, only from reading about the malaise era, they embody the worst of everything; high weight, low power, poor rev-ability, high fuel consumption, barely adequate emissions. It will be very interesting to see how Biden’s new emission rules will be met by US manufacturers this time around.
The industry was overwhelmed by the malaise, regulated to sell inferior products to meet another goal, consumers shrugged.
I’ll keep this in mind in a few years when I have to modify my route and wait on a charger to the tune of 25% more time on every road trip.
The 1975 LS-4 in trucks and the Chevelle (I think) had 215. Can’t find torque numbers, but I’d guess they were mid 300s. The LS-4 in the 1975 Corvette was 270 HP and 380 ft-lb.
