SS/B Barracuda project

FUEL SYSTEM

I was thinking MP 80 gph at 8.7 psi. Mechanical Fuel Pump
3/8 fuel line and sending unite.
Two Bendix electric in parallel.
From fuel pump to carbs are ´68 SS basic.
Also what is correct psi for these Holley Carbs ? Would 7-8 be good, since no regulator was used?

As always, I hope for a comment or advice...
Thanks
