I use the RobBMC for my 393" Stroker and have only good to say. It is well made and delivers 7Psi all day long. It feeds a Holley Double Pumper 750 CFM (4150) and I do not use a pressure Regulator.
Only thing is that for instance the Ford FL1-A Oil Filter can not be used as space is tight. Must use i.e. K&N HP3001 or FRAM HP1 as they have slightly smaller diameter.
