Fuel Pressure Regulator for SN89 on a Ford 200

[duskpearl]

Am seeking opinions on specs for a fuel pressure regulator for my setup:

SN89 through 350 CFM 2 barrel, performance cam, aluminum head and intake. I have the old Paxton manual for installing a Paxton on a Falcon, which shows tapping the backside of the fuel pump to an intake vacuum line and using a fuel pressure regulator (no blow offs shown). But, the regulator is no longer available and I don't know the specs. Any ideas on the specs I need, or on another way to provide sufficient fuel and boost reference my setup?

Thanks.

Pretty sure Summit et al have boost referenced FPRs available. You do not need a specific setting per se, the point of a referenced FPR is to provide carb-appropriate pressure over manifold pressure. I would probably run a return-type FPR and a high volume fuel pump for best performance.
