Re: 327 randomly runs bad
Fuel pump pressure must be max of 4-5psi for Edelbrocks. But, eliminate vacuum leak FIRST--you said you do cheapest checks first. Bet you're gonna find a vacuum leak around base of carb to intake--esp. if you are using some type of adapter. Else, along intake-to-head gasket.
Just another 2 cents worth for free.
