No, but here is some interesting information for you.
Ford 351M and 400 fuel pumps put out about 7 psi if "spot on".
Holley and Motorcraft Carbs can take in excess of 7 psi due to longer float arms with large floats. Carter AFB & AVS & Edelbrock carbs have shorter float arms which is in part why they are more compact, and smaller floats and they are less tolerant of higher fuel pressures, 6 psi is the max that Edelbrock recommends for their carbs which are copies of the Carter carbs. They recommend that a max pressure used at 5.5 psi. High fuel pressure does not mean more power as many cars we considered as muscle cars used 4-6 psi.
You likely need a decent Fuel Pressure Regulator like Holley's # 12-803 and use a fuel pressure tester in a tee between the carb and FPR to set pressure at 5.5 max. Do not waste money on a Spectre or Mr Gasket FPR. Once set you can remove the tee and tester.
