Biased? On the first part, yes. There probably aren't a double handful or less modern, full weight, street driven Gen lll cars in the country that will run with your car in the 1/8. Now if they challenged you to run the standing mile after the 1/8 mile drag race would it be biased to the modern car? Yes, IMHO.
On the second part, no bias at all. I haven't seen any tagged, insured and street driven n/a Gen lll transplants that run really hard.
Understand, that you could outrun every Gen lll in the country and the nut swingers here would still cry foul. LOL
