Hello everyone im looking to replace the carb on my 85 its a 350 crate motor i have the edelbrock performer carb 600 cfm its the electric choke and i cant stand it, its always on the high idle when under 45° and no matter what i do its always rich so its probably getting worn out. Id like to go with a holley manuel choke, any recommendations? Part number? Where to get it?

I know this isn't what you're asking. But I have the Edelbrock 1406 (600cfm electric choke) and it runs beautfully, even as far down as 14 degrees outside, it will kick off of high Idle once I hit the gas and the choke slowly opens to lean out the mixture as it warms. It sounds like either yours is not kicking off of high-idle properly, or your choke isn't opening. A new electric choke element is cheap or you can change it to manual choke.

I have had excellent luck with my 750 Holley 0-3310S. Vacuum secondary, manual choke. It is on my 454. You may be better served with a Holley 600.
Before that I ran the Quadrajet that came factory on my '77 400sb. The Quadrajet performed flawlessly for me. If I needed I could go back to it, but I have the Holley tuned to my 454, so it lives on.
My son had an Edelbrock carb and had nothing but trouble. We built him a Q-jet and he has never looked back. Everyone I know who had an Edelbrock carb had nothing but trouble with it.
There are guys on this board who can tune them, I am not one of them. Maybe one will be along soon and can advise you on your carb.
But in a nutshell, for me.........
Stock engine-Quadrajet
Go fast-Holley

I don't think this will resolve your issues. Did you set the choke, fast idle speed, timing and idle mixture screws?

Dually buy a calibration kit for your edelbrock

Everything was set on the carb not too long ago the truck does run fine im just sick of the electric choke ive always liked manuel chokes so i wanna go that route, ive never had good luck with these edelbrock carbs ive had several trucks with them but they may have never been set up right

You can buy a conversion kit for the carb and make it manual if that's what you want
