carb issue

[RUNCHARGER]

I have about the same luck with Holleys as I do Edelbrocks. For your application I think a totally stock 3310 should work quite well. If it was mine I would get some gaskets, pull it down and dip it. Blow air through everything and assemble it with all the parts and settings that Holley calls for out of the box.
I did that with one on my nephews stockish 400 and he bolted it on and never looked at it again.

If I member correctly Quickfuel does most of the design work for Holley.. Holley has bought up most of there paten engineering..
But for some of us Older guys who can't break away from the OEM that may or may not be "Numbers matching" I get why you'd want to rebuild your original.
Love it!

Sorry guys.  I'm working 15's right now.  Only get a chance to drive the car to work and home.  But I will go through the help from y'all and work through it.  And comment a little more.  I appreciate the help leads to follow up on.  I will let you know what I come up with.

Off to work.

Holley bought them out. I worry about the quality suffering since the buy out. When Quick Fuel was up and running you could call them and they were really knowledgeable about every aspect on how to correct certain issues. Would take the time and help you out. Now that Holley owns it you get the vanilla answers from somebody siting at a desk with better things to do. If you get my drift.

Just looking over the 70' Challenger Shop Manual, there's a really good section on the Holley 4160, how to set-up everything. If you can read at work or on your down time it'll all come to you.

Do you know anyone that you could borrow a similar carb to yours and just bolt it on and see if anything changes before you try making multiple changes to yours. If it's the same with the other carb, then it's not the carb at all. Just an idea?....

   That's a great idea.
