First track run - less than exciting....

Hi Joe...thx for chiming in.... Its a 3800 converter the lean out is far worse when I stall it up....probably because it uses up some of the pump shooter travel when you stall up.


I really appreciate the feedback guys...at least I know what Im dealing with.


Here's a thought......did anyone experiment with a divider in the intake plenum?

Dors anyone think a partial divider might help?

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.
