Hey gang,

I'm putting together a 292 with 3 rochester monojet carbs using offy manifold and progressive linkage. Need to buy a electric pump. What is ideal pressure and how much volume do I really need? Looking at a pump that is 2-3.5 psi and 28gph. I read that 3 psi is ideal for the little carbs, but will 28 gph be enough when I've got my foot in it and all three carbs are WOT?

You should be fine, Or you can go with something a little bigger and Just put a regulator and pressure gauge on it and set the psi.

28 gph should be good for roughly 320 HP. As Twisted said You're fine.
