I am working on my 67' Cutlass Supreme.
I have rebuilt the top end, and am looking at replacing my old carb rather than rebuilding it - I believe the car was originally the high compression, 2 barrel carbed 330. However, it came with a quadrajet which had the circular stamp removed. I think it was originally a 2 barrel as the old pushrods did not have a blue line on them.
I was curious, since the carb is not original, and is in pretty rough shape - I would like to find a performance carburetor to go ahead and work well with the modifications I have made.
I have very lightly polished and ported my heads. VERY lightly.
I also have a new cam, slightly higher duration than stock but a slightly lower lift. Along with the cam I have new 8.5" pushrods (~2% longer than stock) as well as new hydraulic lifters and 1.6 ratio rocker arms. I have replaced the air breather/filter with a "performance" brand, and intend to replace the intake manifold sometime in the future. Besides those modifications, it has the A/C system removed, as well as upgraded distributor, ignition, and timing gear set (now a double roller).
Could anyone recommend a decent aftermarket carb which won't break the bank which should work well with my current build as well as with a performance intake?

 

Quick Fuel 600cfm "Slayer" series. Loaded with features and tunability and it won't break the bank.

 

I don't mean to sound stupid but what do you have for an intake on this engine now. I'm guessing you have a stock Q-Jet manifold and if so I'd look at 650 vacuum sec. Holley, Holley does make a replacement carb for that set up which is not a direct replacement but pretty simple to change over, I have used these on several engines over the years or you can change to an after market manifold with a 9834 Holley.

 

Right now the intake on it should be the stock intake, stamped 344741-3 if I recall correctly.
Thanks for the recommendations you guys.

 

heard lots of good things about Quick fuel........kinda wish I knew about them before I bought me eddi 750

 

Street Demon 625, based off the Thermoquad but all news castings with the problem areas fixed. It will bolt right to your Qjet manifold.

 

I appreciate the input. I do believe I am going to go with the Quickfuel 600 cfm "Slayer" based upon various reviews and the recommendation - provided I can find a mechanically controlled one.
All I was able to find through their website and the regular company I order through was electronically controlled, it seemed.

 

They don't make the Slayer in a mechanical secondary. You don't want that anyway with your combo.

 

Ah, I think I am confused. I knew I wanted a vacuum secondary, but I see that it has an electric choke, and I thought I saw some photos where it looked like the throttle control was electrically controlled as well - but now that I revisit their site it appears I may be mistaken (at least about the throttle control).
Will an electric choke be fine then?
