DIY not a mechanic looking at all the pitfalls before I begin the next project - switch from Edlebrock performer series to Holley Dual inlet 4160. Need advice on fuel lines (pump to carb) for '67 Coronet with 440, TF, stock intake manifold, aftermarket headers, Lunati cam and I recently updated to electronic ignition. Currently lines plumbed for Edelbrock performer 600 single inlet. Just for the heck of it, if I wanted a Holley 750 cfm 4160 (dual feed inlets), how much plumbing headache will I have? I don't have a Holley, yet. I'm afraid that the usual dual inlet chrome line for $20 will bump into the distributor. or coil. No return lines on this engine. If you've tried / done the conversion, looking for your advice.
