On the way the freeway yesterday evening, running about 75 mph in my cobra, and a red GTO comes flying up behind me. The cobra is a few hundred miles into it’s second oil change post engine rebuild and this is the first chance I’ve had to really push it. Full exhaust/bolt on, 10:1 comp, tune, etc, stock gears. I waited for traffic to clear and got over one lane and he gave me a good old fashioned ricer fly by. I laid into it through third, and was within a couple car lengths before shifting into fourth. I pulled the nose past him at 140 mph, and decided that was all I needed and slowed down. He never let off and I’ll assume he was in the neighborhood of 160 mph when I lost sight of him. I’m guessing I’m probably at or around 330whp, so is it safe to assume the Pontiac was stock short of exhaust? I’d imagine he still had a small power advantage, but is at least 500 lbs heavier.
