270Win--
I recently purchased the Summit brand. I had trouble finding a spot to mount it and wound up mounting it on the front of the engine, passenger side. This was not a problem for me to do as I have no AC in place and don't expect to have any of the compressor and brackets mounted for some time (may never again). The vac hose from the unit runs along the heater hoses and they runs between the back of the carb and the distributor over to the filter and then on to the brake booster. I have not set this in permanently at this point and could take it out in 15 minutes or less. As for wiring, I tapped into the HEI power (pink) line and the positive wire runs along the passenger valve cover to the unit. The negative is attached to the ground strap on the firewall near the distributor. There is a built in 12 Amp fuse on the unit.
My power brakes were not receiving enough pulse to properly operate my 4 wheel disc brakes. It felt like a manual. Mods to the engine reduced the vac. The increase in vacuum made a big difference.
As for noise--it runs intermittently and only for several seconds. Not an issue.
Hope this is helpful.
