Actually the drive train is VERY streetable. The engine will idle at 800 rpm, and the converter will WOT stall about 4,000, but it will still work on the street. That same converter had a 3,000 stall behind my 170 motor, so this motor has a lot more torque. The 3.91 gear is ok for street use, with a 26-28 inch tall tire. I run a 22 inch slick, which gears it down lower at the track. There is still the ability to run a bigger cam and more compression. Also head work (porting, big valves). This was built on the premiss of low dollars, upfront and then upgrades later on. The way most of us, on a budget, have to build a car. One major thing to remember is, the car only weighs 2680 lbs, with me in it. My 66 Cuda weighs 3250 with driver. So everything else equal, the valiant would be at least a half second quicker in the quarter. The Car itself is not streetable. All strett equipment except for tail lights, and glass has been removed.
