In the 1960’s there was a major horsepower war going on between the big three automakers, along with internal battles between each automakers own brands in some case. Buick, one of GM’s interestingly versatile brands, was well known for making performance machines that had a refined edge. They weren’t bare bones power makers like the Chevrolets, but more of a gentleman’s hot rod. And because of their engine designs, Buick’s were never quite the horsepower monsters that Chevrolet had created, but that’s because low rpm subtle grunt was more appropriate for their market. But if you wanted to sell a Buick GS to a gentleman looking for a hot rod, it still had to move out and be able to smoke the tires at will. We’ll, the way to do that was with torque, and lots of it. In 1970 Buick had the highest factory rated torque, at 510 lb ft, of any factory big block ever offered. It is still the holy grail of torque ratings and is bragged on by Buick and GM fans everywhere.
But how do these big block engines from other manufacturers really stack up. Not specs from the people trying to sell you one, but from the engine dyno that doesn’t care who is bolted to it?
Well there is nobody better than Richard Holdener to do such a test and we’re excited as hell to see just how this video pans out. It’s the ultimate big block torque test, with the Buick 455 facing off against the 454 Chevy, 460 Ford, and 440 Dodge. But who will reign supreme? And will a few bolts on make a big difference?
