Roots Centrifigul Screw Superchargers Roots Type Blower
|
Just for the record, Roots-type blowers such as this Holley/Weiand unit work really well with stroker cranks in smaller cube engines, such as a 302 Ford (out to 331 or 347) and 350 Chevy (out to 383 or 408). The trend for best Roots blower results when building from scratch: more cubes and less boost work better than less cubes and more boost. Eight pounds of boost in this 347 small-block Ford produced results comparable to a 418-inch stroker motor. View Related Article
