In watching recent NHRA events ( youtube ) I see older engines in later model cars. Example: 64 cross-ram in a 67 belvedere. Cheby 283 in an 81 Camaro. The window designations appear like SS/AM or similar. Is this an original advertised HP with the later model weight ?
In advance, thanks to anyone who can clarify this as I'm getting nothing off the NHRA website ... or I'm looking under the wrong areas.
