I would suggest that you call Ben directly instead of email. (317-484-1451) I get a quicker response by calling.

Not a problem. Maybe give Ben some more time to respond. He usually gets back with me in a day or so on email.

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?

yes it is correct no fitting on the side.

hook it to the intake manifold for full vac maybe
use a carb spacer that has a port for vac line
timed port may not be an easy thing to add if it does not already have it

I guess it was wasted money to buy Promax metering blocks, If i will have Vacuum to the distrubutor I have to take it out and put back my old original holley.

Quote:Might experiment w manifold vacuum & see if you can get it to work. Yes I (& most) prefer ported but above idle the amt would be the same so I would think you could get it to work & therefore not waste your (Promax) investment and a carb guru might be able to talk you thru drilling the base to add ported. Good luck on it. EDIT or possibly drilling the Promax. I'd think there'd be a (ported) source inside there somewhere. I am not a carb guy. Have you emailed Promax.

Well, I would'nt go as far to say it was a waste in buying the metering block...You do have a high performance engine that needs the block right ???? 
You don't need the distributor advance for a performance engine...If the engine is close to stock and you want the fuel economy of the distributor vacuum advance then that's a different story...I run the Promax block and don't need/use the vacuum advance...For all out performance it's not needed... I was thinking about adding the channel to the promax block just as an experiment but that's all it would be....Here's a link to a previous thread that shows the mods needed to add the vacuum port...Not a small job... link ...The vacuum advance comes into play at part throttle or cruizing RPM so the spark has more time to completely burn the fuel...You'll get a little more distance out of your fuel but who cares about that when your
