Ditto DV.... Build for low end and midrange torque. Something that will pull from 1500 to 5500 RPM. 383 or 406c.i. Built 700R4 for two reasons. 3.06 1st gear and 0.7 Overdrive in 4th. Run a set of 3.90 or 4.10 gears with some ET Streets and I guarantee you will have a tuff to beat combo on the street and it will still be very drivable on the highway. And don't be suprised if it pulls some decent milage numbers also.
