Converter and Carb.

[69fourspd]

I have finished getting the engine together after swapping cams and springs per Firefighters advice, and am ready to get the converter and Carb for my 440.  The carb I have is going on another engine, so I will be in the market for the best bang for the buck.  Also, I will go with the PTC converters Firefighter recommends, just need to pick what stall and size to get. 

Thanks for the help!

I would be looking at an 850 CFM carb , The Holley Avenger 870 vac or 4781 DP , unfortunatly they don`t make a street HP series carb in an 850 , only 750 or 950 , the next choice would be a Proform 850 DP

Proform 750dp and an 11in PTC converter.

Thanks guys.  Can you tell me how the proform will be for tuning?  I am pretty ameture when it comes to carb tuning, so will this be a good option to bolt up and make minor adjustments?

The proform carbs are easy to tune. These have a 4 corner idle and adjustable air bleeds....but you won't have to mess with the bleeds at all for your build.    The 750cfm Proform double pumper actually flows 830cfm as measured on a flowbench.....it will be plenty for your engine combo. I have the same carb on my 446 and it made more power on the dyno than a holley 850dp. The throttle response is much better due to the smaller venturis which creates increased signal to the boosters....thus making the engine more responsive.

On a build like yours it should be pretty close right out of the box ; adjust idle mixture, idle speed and float levels and that's it. The jetting should be bang on "as delivered".

That sounds great.  I will put in the order.  Thanks again everyone! I will keep you posted when I start it up the first time.
