is there any of you using Promax metering blocks that can tell me where I shall put vacuumhose for ignition, has written to Promax, but they do not respond.

I'm not so good at talking your language

anyone

I dont own one but trying to help. I'm assuming that they dont have a stock (ported) fitting on the side like stock holley metering blocks do?

thanks for your response.yes I have written to Promax 2 times no response, it is probably best if I remove the Promax block and use the old holley, the car runs most on the street and our gasoline prices here in Sweden is more than double yours so I do need Vacuum advance.
