I have rebuilt my engine from the crank shaft to the top. My block has been bored out, triple seat valve job, new valves, wild crane cam, four barrel intake manifold from arizona z car, and a holley 390 carb. I took it to a shop that i trust to have the valve clearance, timing and all that stuff that i dont know how to do, done. When its running it runs smooth And it will idle forever. But i cant let it go down to idle speed or else it dies, and it dies after driving it half a block. I think it might not have enough fuel pressure for my four barrel but im not sure. I only have the mechanical fuel pump. If anyone has any info it would be greatly appreciated.

(does anyone know what the holley 390 requires as far as fuel pressure???)
