Originally this engine was built by Bob Wallace for a 312P (Flying Shingle, ex-Chinetti). We rebuilt it once in 4.0-liter form, then again as a 4.5-liter. It is a unique motor with handmade slide valve Lucas Fuel injection set-up. In 4.0-lliter form it dyno’d at 338 HP @ 7,100 rpm. We improved the output by increasing the displacement and re-porting the cylinder-head to our specification. The result was 419 HP @ 7,300 rpm. The next step is a 5.0-liter conversion.
