I've bounced around the idea of building an s10 for the street and with the lightweight of the truck, huge amounts of torque off the line will just shred the tires. if you push your power higher in the band, the truck will scream on top end. then you can match your gear set to what you need as well as a stall converter. Build the motor for max HP and forget about an torque numbers. Make up the torque in reduction via gearbox and rear axle.
