Mauler 440 Engine Wilson Spacer
|
We next added a Wilson 1-inch spacer between the carb and Indy two-plane intake, reasoning that top-end power would be further improved. Power was up noticeably from 5,800 rpm upwards, with peak output rising to 640 hp at 6,300 rpm. Torque dropped slightly below 2,800 rpm, but tracked nearly identically from 2,800-5,800 rpm as compared to the intake without the spacer. View Related Article
