In ‘04 the SAE revised their rating system again. The 455 horse in modern Camaros is a realistic number. Those old muscle cars felt fast but realistically they were slower than a modern V6 Camaro.

That 450 hp header mod must be with unicorn dust.

If you connect an old M22 to a modern LT1 the LT1 would shred it to pieces.

I can assure that you that a modern LT1 would not immediately destroy a M22, you may break it eventually, but you certainly wouldn’t shell it the first time you dumped the clutch. In fact, you would have a hard time hurting it on street tires. A toploader would likely live forever behind an LT1.
