What do you think the most HP someone should have for a street drive?

[Unit 5302]

Sorry, I missed the carb comment. The carbed 450hp setup is a bad idea for a daily driver. Real bad. Carbed engines generally rev better and make more horsepower than their fuel injected bretheren when setup properly, but they sacrifice low end torque, fuel economy, and drivability.

He'll have to go with a 351 stroker (377ish) if he wants to make 450-500hp with a N/A carbed setup that's streetable, and it'll have to be a moderately aggressive setup at that.

Fat0eknee I don't disagree that 400hp is unusual or more than you're going to be able to fully utilize on the street, just at the concept of the 400hp car being difficult to keep control of. The DOHC Cobra's, when supercharged, can make 450hp without much else done to them, and they maintain drivability, too. That being said, I do agree with you if he plans on going N/A and carbed. I had a Honda CR500 2-stroke dirt bike a year or so ago. Tons of power, but the powerband came in so quick it was difficult to keep under control. Same case with a 450hp N/A small block. Expensive as wack, too.
