We live in the Golden Age of horsepower.
Indeed. I was a red neck hot rodder in the 70s..when the guys that had an honest 400+ HP under the hood were the kinds of the road. The 327-365 in my '57 Chevy was an evil running engine, for example. But it ran like poo on anything less than 100 octane fuel too.
The engine in my Pantera is fairly old school; built in the 90s by a Pantera race prep shop, its a 351C with 4 Weber IDA 2V carbs and 2-stage port-injected NOS. On the second button, it was dynoed at 725HP. On just the carbs alone, its right at 400HP, 70HP above what the stock Pantera engine was. By today's standards...that's a pittance.
If money allows..I'll have one of those 800HP all-aluminum Clevelands in the Pant some day. Or not..;-)
