Okay, so I go and buy a new regulator since obviously mine old is failing. I put new regulator on and still shows 9psi even though its turned down to 1psi. So at this point I dont know what right or wrong. Regular is only adjustable from 1 to 6psi. My pressure gauge is brand new, I was going to get new pump as well since old one is 4-7psi. I thought if I have 9psi then the pump is bad as well, however pump is only 2.5 months old.

So to check my pressure I simply remove fuel line from carb, and plugged it up to Vacum/Fuel pressure gauge and get almost 10psi. I bought a new mr. Gasket regulator and turned it down to 1psi and it makes no difference. I haven't checked pressure In-line with engine running. I figured the regulator should keep pressure down 100% of the time. At 10 psi to carb. that seems to me it is to much and can be unseating my valve seat allowing carb to overfill. Any thoughts??? Maybe buy a better regulator???

This is just me thinking here, but if you are going to buy a new electric fuel pump and regulator, why not just buy a mechanical fuel pump for much cheaper and it will supply the correct psi. As for the carb, I would get a 650cfm to help the 460 breath easier. It really doesn't matter what brand you use. You had an Edelbrock on before, I would stick with Edelbrock. Should be a direct replacement. The Edelbrock 1906 is $370 at SR.
