This is one of our typical blown pump gas, street small blocks. You can expect anywhere from 500-650HP out of one of these, very reliably, and very tame on the street. Great for street rods, cruisers, pro-streeter's and even boats for weekend water skiing with plenty of power to pull several skiers and enough reliability to run all day without a hick-up. Of course we can configure ANY engine with just about ANY options you can think of, and adjust the price accordingly. That's the beauty of getting a custom built engine.
