My .030 over 440 makes 643HP at 6300RPMs and 592lbs of torque at 4400RPMs.
If the motor is put together with the right parts,IE good cylinder heads and cam the motor can be very streetable but I would not want to drive my car in the rain.
If someone thinks they are going to build a 500ci 650HP BB with eddie RPM heads and it is going to be a nice street motor they are wrong, You would need lots of compression and a big cam and those two things do not work well in a nice street car.
The reason my motor makes the power it does is a lot of little things that adds at the end of the day, most of witch are stupid for a street car, but Iam a gear head and I kind of went over board with the motor.
