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

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.

They are almost done with my brother in laws 90GT at pro-tech in Lubbock TX.

331 dart blocked turbo charged. It will make 650RWHP with the street tune and is capable of 800RWHP. This car will be a daily driver.

I will be posting pics soon.

If you are going to go through an engine change you might as well just order a 514 from the Ford catalog. I think it has everything but a carb. Drop it in and you will have 650 HP. You wont have to deal with all that other crap.

By the way 500 hp is alot of power for a daily driver. I got about 500 with my 428 and i don't drive it except on weekends. It would be a real pain in the butt to drive everyday. It is alot of fun to have that much power but it is a very rough drive. You have to really stiffen your car up and it rattles everything htting bumps sucks bad. It really sucks bad to drive in the rain. i can't even count the number of times i spun out in the rain barley stepping on the gas. I suggest you get yourself some 500 dollar piece of $hit to drive around in then build your race car.

It's true. There is no magical hp number that the stock block is incapable of exceeding.

That being said, not all blocks are of equal strength, and unless the entire setup is balanced, blueprinted, modded to make sure there is serious vibration reduction, I wouldn't want to use the stock block in applications of over 450hp.

Too many people put their parts together in a stock block and don't do the additional work to make sure the main webs won't crack from balancing issues. The 5.0HO block is not beefy by any means, and I don't think pushing the limits of what it can take is a good idea with a daily driver.

I would expect that a N/A 306 would probably be capped in the 550-600RWHP neighborhood. Of course, it would be an engine that would cost a fortune, have serious streetability issues, and longevity issues. I like 9,000-10,000rpm redlines too... but I'll keep them on my bike for now.
