Holley 4180c Upgrades

Hey gang, the 83 project is finally making noise again! I got the suspension all back in, alignment set, new brakes in and bled, and the Holley 4180c carburetor rebuilt to get it running again after its 6-7 year hibernation. The carb runs beautifully now and I'd wanted to share my parts list in case anyone is looking for information in the future on what to do with these things:


  • Carb rebuild kit: Holley 3-1346 Carburetor Renew Kit
  • Holley Secondary Metering Block Conversion Kit 34-6 Holley 34-6 Metering Block
  • 30CC Accelerator pump diaphragm: Holley 135-5 Rubber Accelerator Pump Diaphragm
  • Accelerator pump squirter: Holley 121-131 Straight Accelerator Pump Discharge Nozzle
  • Nitrophyl floats (x2) Holley 116-1 Nitrophyl Side Hung Float
  • Holley Viton Inlet Needle .110 (x2) Holley 6-504 Viton Inlet Needle
  • Holley Jet (primary) Holley 122-63 .062" Carburetor Standard Main Jet - Pack of 2
  • Holley Jet (secondary) Holley 122-72 Standard Main Jet - Pair
  • Single stage power valve: Holley 125-105 Single-Stage Standard Flow Power Valve
    Many thanks to the guys hanging out over on http://www.foureyedpride.com. That's where I gathered the information to put this parts list together.
