has patent numbers didnt see a model number. got this with adapter plate and a vacuum dist. from my dad. might install tommorrow. also if anyone has a diagram for vacuum ie. brake booster, pcv. and where adjustment screws are. never had a holley.
looks like a basic 1850 style carb. single feed line, 600cfm vacuum secondaries. Adjustment screws are in the front on the metering block and there is only a single port in the back for brakes. There should be a little nipple port for the distributor somewhere, although I can't imagine this adding any HP over a factory carb which is around 750cfm stock.

having trouble with current ccc. need to get car running. also where would the pcv hose hook up to? only has one port in right rear
Usually with Holleys, you'll end up using the port on the carb for PCV, and a fitting on your intake manifold for the brakes.
Also, that carb won't work with the factory intake manifold... thats a square bore carb (all the throttles are the same size)... and a Qjet is not like that. You'll need an adapter or new intake to use that carb.
my dad gave me an adapter. he pulled the carb off a chevy p/u and was used about only 2 months. there is a smaller port on the manifold behind the carb.
ok found out its a 4160 remanufactured 65-80457. now does anyone have any pics where to hook the brake booster to? there is a port between the carb and dist going to the firewall. the port is smaller do i tap into that with a "T"? dont really feel comfortable tapping into pcv line.
I don't understand what port you're talking about. There is usually a port on an intake runner behind the carb that you can use for the PB booster. I'd use the port on the carb for the PCV, myself. Depending upon the adapter, you could possibly drill and tap it for the PB port as well.
If we're talking about the same port on the intake manifold, find a fitting that screws into the manifold, with the proper nipples on it to connect the PBB and existing vacuum line.
TH700, right? It's a "throttle valve", or "TV" cable. It needs to mimic the original geometry. Holley makes the proper pieces for it, check on Summit's website.
you can make your own block off plate with some thin guage steel and some paper to trace the shape onto. Then drill two holes and seal it off with some rtv and the 2 factory bolts. Took me under 30 minutes to make my own one day on a car.
