i just ordered on edelbrock performer carb for my 1964 cadillac i was wondering if any one has any tips or knows of any problems i am gona run into or better yet solutions to those problems. thanks for helping my out.
I think the fuel inlet's different because the Edelbrock is based on the Chevy version of the AFB. Shouldn't be a big deal to relocate.
Eddies are good carbs out of the box...I've run several over the years. Just like any carb you will need to set it up to run on your motor, so a good vacuum guage and timing light will be necessary. Make sure your ignition is good shape and your vacuum advance, if you have one, is opperating properly...oh and also watch which port on the carb is "ported" and not "manifold" vacuum for your dizzy line...been there done that...Doooh!!
If its the same as a 65 (think so) the stock carb runs a cast iron base plate and the exhaust crossover runs exhaust gas right up to and around the baseplate. With a squarebore carb and spreadbore adapter the ports are uncovered and the exhaust gas runs back into the intake and poisons the incoming air and fuel mix. Found out the hard way... With a spreadbore the holes are probably covered but the heat can't be good for an all aluminium carb, heating the fuel etc.. A tap and two small pipe plugs fixed the problem. Also... I think the ****erflys are spaced different than a standard spread bore or square bore... can't remember. I ended up making my own adapter/ spacer to fit a Holley on. Hope that helps...
On the Carter and cloned twin Edelbrock carbs, manifold vacuum to the vacuum advance can is supplied by the left front bib (small and on the drivers side in the US). Ported vacuum is the right front bib. If there's only one bib - on the right side on all the ones I've seen - it's ported vacuum. You can also pick up manifold vacuum at any other source on the manifold proper. Manifold vacuum will help your car run cooler in traffic and at idle. Ported vacuum was a GM development to make the engine run hot at lower speeds to help the smog situation. Ported vacuum used in hot rods almost always leads to overheating.
thanks every one for the help i found out all about it hear if any one else is wondering about the same deal http://6364cadillac.multiply.com/journal/item/9
For my '64 Pontiac, it was a total bolt on, all vacuum ports are there. Only thing different was where the fuel line went in.
