And probably a thousand pounds lighter than the B bodies too, great combination for a fast car :)

Agreed, same motor, different car = different ET's. I have beat several Corvettes (60's) and 5.0 Mustangs. Knowing your car also has a lot to do with lower ET's. While the big boys are back at the line, smoking their tires, I'm at the end, waiting for them to catch up.
