As a mechanic who specializes in performance car parts, i was disappointed with this carburetor's performance.It didn't deliver the horsepower gains I expected, and its consistency left something to be desired..

Pros
  • None
Cons
  • Poor performance, inconsistent results

New & Improved Design

This gasket added a stronger vacuum signal to my dueling Holley 750cfm 4150 feeder You may need to enrich the fuel mixture like me, more air = more fuel. Modified Ford 390FE. Hopefully this one doesn't melt like the old plastic product I bought. Now the HVH website says the plastic model is for drag racing only and I will not get my money back.

Pros
  • Packing Weight: 1.98 lbs
Cons
  • Quick Start Guide
