First track run - less than exciting....

Due to the difference in the "K" value I was curious to know what the physical size is. You can have an 11" converter stall at 3800 rpm behind a 640 CID 950hp beast and the same 11" converter will only stall at 1800 behind a stock 273. My six pack was sort of like that. I think youre issue as you know is purely vacuum signal to the carb and a good Holley should be able to be tuned through it. I have had my dealings with Carters and Eddys. There are just some things that can be done with a Holley that can't be done with a Carter/Eddy. We have one of the most modified Carter AVS carbs on my friends F.A.S.T. Dart and it was a total bear!! I mean bored out for bigger throttle plated and completely modified and reworked within class rules.

Hi Rat I was refering to the part where HJJ said (quote there are some things that can be done with a Holley that can't be done with a Carter .

I'll try to explain . The double pump Holley has two accelorator pumps and four nozzles , 'one for each barrel' , and each is adjustable for duration and volume . So there is a lot that can be done to cover that lean bog when the pedal is smashed to the floor and the slicks bite the track .

The Carter only has an accelerator pump for the primarys , so when the bog occurs you adjust by slowing down the opening rate of the air door , to suit your gearing , convertor , vehicle weight , and engine torque .

You might find the bog free setting but it will likely compromise your 60 ft times .

Hey i'm not an expert here , so maybe start a" Carter vs Holley for drags " tread in the fuel air systems section of the forum .
