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.

My 69 383 RoadRunner had more lowdown grunt that my old V6 11 Camaro. But my Camaro was geared lower and had more top end than my RR. I' m pretty sure my 383 was more powerful than my V6 Camaro but my Camaro had 3 more gears than my RR too. Coming out the Hole I think my RR would win but after 65 or so the camaro would walk it. But if that RR had an equivalent modern 6 speed close ratio manual trans, I'm pretty sure the RR would lay waist at least to 100mph.
