One way to run 10's with 400+hp 2.3L Turbo Ford:

This is a pretty good description of Joe Morgan's car.

1. Buy a Pinto (2500lb w/mild steel rollbar and subframe connectors,
     without driver), and put this motor in it.
2. C4 automatic transmission, stock ("F29") torque convertor.
3. 4.62:1 gears and a locking differential in a stock 8" Pinto rear end.
4. Use the N2O system right off the line to eliminate lag.
5. Use very sticky tires for consistent low 1.5xx 60' times.
6. SPA-1 Koni shocks, and home-built leaf springs with Global West bushings.
