I picked up a Weind T/R with 2 Holley 390's I believe? might be 360's ... Anyway I was wondering what fuel pressure I needed to maintain for these little guys to squirt like a big dawg? Im wondering if a stock fuel pump would handle them... Seems like it should, Oh its going on a 67 327 double hump motor.
Thanks in advance
4-6 PSI is about all a Holley likes. As for a stock pump, would handle the pressure ok, not sure about the fuel volume with 2 carbs dumping gas at any sort of RPM..... Holley, Edelbrock, Weiand and a number of other companies do offer a hi-volume mechanical pump, though!
5 - 5.5 lbs is preferred for carbs, and be sure to get a regulator rated for dual quads.
Perfect... thank you sir! Im sure I have a couple liquid filled pressure gages laying around here somewhere.
