Title: Holley 4150 carb spacer plate ?
Post by: orgnl70 on January 28, 2023, 03:52:47 PM
67 S code, C6 trans, AC.  I bought this car in parts. There is a "Bakelite" carb spacer with a single vacuum port. Is this correct for this car? Where would this be connected to? Also would anyone have a picture of the fuel line to carb connection?

Did your car come with a thermactor system ? A set of Osborn assembly manuals would be a good investment for a car in parts.

Car did come with thermactor system. I have the Osborn manuals but there are no referances to the carb spacer or its connections.

There was the spacer still looking to see what one was used and if it was attached (vacuum line wise) to anything. Pictures are from  a thread in the Unrestored picture thread that focuses on a late 67 San Jose 390 with Thermactor that was unrestored

As for the routing from fuel pump to carb its shown in the picture below basically. Attachment to carb is the typical solid in, short piece of hose with band clamps (not the replacement style show) and them to the filter attached to the front bowl of the carb

The factory spacer was about 3/8" thick and had a quite fragile bakelite nipple coming out the back side towards the fire wall a short piece of rubber hose would connect it to the steel line that went to the C6 modulator valve on the transmission. The carb spacer would be in the 67 engine assembly manual which can  help if your going to use the AC and air pump power steering to.
