My 1965 project Old Mobile 442 build

are you 100% certain your secondaries are opening on your quadrajet?

I have 2 street avengers - they're okay, but good thing they were both cheap (used).
You might consider an 850 carb?
I have an (IIRC) 850 holley with a proform body - I really like that carb, downleg boosters are pretty good

and last thought - you mean 242/272 cam? It's been awhile since I was in school, but the longest (with the old math that I learned) a valve could be held open was 360*.... but who knows, maybe they have a spiral cam that allows more?

I'm 100% sure they arent opening, but it isnt due to low vacuum. The cam is 242 duration 572 lift

linkage is good?

wow, that's a decent lift...

Holley has a great tech line - have you run your numbers by them to see what they might suggest?

on the passenger side of the carb is the choke setup. There is a lever that keeps.the secondaries from opening when the choke is closed. Make sure that it not stuck or out of adjustment. Also, the secondaries air door at the top of the carb has an adjustment that is spring loaded. There is a screw on the side.that adjusts the spring's tension. Below that going up is an allen head set screw that you have to loosen first. The spring should keep.some tension on the air door. You dont want them to flop open. Be very careful not to overtighten the spring and break it.

My '70 Caprice's Quadra bog is sitting in the storage closet. It worked fine, but I replaced it with a Holley 3310 almost immediately after I bought the car. I even let a friend use it for three years on his chevelle.

I am seriously considering buying a carb from Patrick James from Prosystems. Any one using his carb?

[cantvalve16]

Never personally used one, but have read about lots of people on a variety of forums that have. I have never seen even an internet complaint about his products.

Thats one of the main reasons I was thinking of using him, and on top of that I have heard compliment on top of compliment about his customer service. It seems he takes calls all weekend long and all hours of the night on his cell to help people.

Well.... I didnt like the looks under the hood, nor the finish on the intake/valve covers so I opted to do a little "changing" things. I smoothed the valve covers, used a different paint and VHT coating. Got the Pro Systems carb, changed the wiring. Added some AN style fittings, ordered some brackets from billet specialties, changed plug wires, I am now waiting on a new Dist from pertronix with the rev limiter.

another 12 hours in the garage and it looks like I have done very little GRRRRr

[SuperBuickGuy]

yes, but you're 12 hours closer to driving it

I'm still hungover from dragweek - but, I don't see any breathers, or pcv ports in either valve cover, what am I missing? I see the oil fill up front.

PVC port on the righ hand side cover....

close Joe, it's on the right hand side in the intake manifold. stock manifolds they're nearly in the center behind the carb

Actually there is a pcv port we added to the Edelbrock intake right in front of the carb and a port on the passenger side valve cover.
