Big Block Chevy Engine - Battle Of The Boost
|
With the Weiand 177 mini blower we were able to clear a Pertronix HEI distributor, while the 8-71's tighter fit required a regular-diameter MSD distributor. Those low-style B&B valve covers cleared the Crane 1.7:1 roller rockers and helped keep the mini blower from looking too dinky. The carb used in the naturally aspirated testing and with the mini blower is this Holley PN 0-80574S, an 800-cfm blower-tuned double-pumper with a manual choke. With the blower it ran with out-of-the-box jetting. View Related Article
