Holley 0-81870 Street Avenger 870 CFM PERFECT CARBURETOR!!!
By B. Higgins
I just finished installing it on my 1970 Corvette 454/465HP motor. FANTASTIC!!! It is the 1st carburetor that I have ever installed over the last 50+ years that I did not have to touch other than a slight 1/4 turn out richer on both fuel/idle mixture screws and about 1/2 turn in on idle speed screw to increase the idle RPM! After a trial run, I can say the throttle response is crisp, no flat spots, vacuum secondary opens immediately at WOT with no hesitation lighting up the tires! PERFECT carburetor for a built big block aluminum head Corvette with an automatic transmission with B&M 10" race converter and shift kit with 3.73 to 1 rear axle ratio. I need more tire now!!![...]
