I love 460's.
One has been carrying my *** around for the past, almost , quarter of a century.
What a reliable and torquey engine.
If you want to make good horsepower numbers for, relatively, little money, the big block will be your best choice.
It's pretty easy to get 500 hp with a perfectly streetable set-up.
Two problems with the engine:
It's heavy. It was always the heaviest of the "modern" big block V8s. But it's strong.
They don't "breathe" very well. More of a low RPM engine. But 500+ ft lbs of torque is fun when it hits at about 2500 RPM.
Both of these problems can be helped with the addition of a set of aftermarket aluminum heads. That starts to get pricey though.
I've never driven a 460 Fox, but I'll bet they're nose heavy.
I think, if I wanted to build a car to go fast in a straight line for cheap, the 460 would be a viable option.
If I want to go around corners fast, I'd stick with the small blocks.
