Re: Stock manifold-carb question
I’ve run across 4 in my time,
Two made 7 psi, one 9 psi and of course the 11 psi 62 Pontiac superduty dual quad 421.
Think about this Al.
If fuel pumps never put out more than 5 psi, why would Edelbrock market one that’s set at 5.5 to control a pressure problem in their carbs.
