Just thinking about the old SAE gross ratings of the original muscle car era and I had a real mind blower…..
If our 455 hp LT1s were rated in gross circa 1963-71 it’d have been rated about 570 hp!!!
Those of you with the 650 hp supercharged LT4? 810 hp!!!!
Take that Chevelle SS396, Charger 440 Magnum and 426 Hemi, and Ford 428 Cobra Jet
