Holley carb to Edelbrock carb?

Ok, I have a POS old 4 barrel Holley on my 392 now and I want to switch to an Edelbrock Performer carb, does anybody know if an adapter will be needed to do this swap and what I will need to hook up the linkage for the throttle and the kickdown? Edelbrocks website is down so I can't get any info from there unfortunatly. If the adapters cost too much and it is a big pain in the ass to get the linkage hooked up I will just go with Holley's Truck Avenger carb instead. Thanks a lot!

Re: Holley carb to Edelbrock carb?

I have a 392 with an identical setup. I did not do the carb switch though, the previous owner did. There should be no adapter necesarry. I don't know how different the kickdown linkage is. I do know that the edelbrock is a very good carb, I love it for my purposes (mostly off-road).

Re: Holley carb to Edelbrock carb?

Yah, Edelbrocks are very good carbs, thats why I want to ditch this POS Holley, the thing bogs down when ever the truck is anywhere but level ground. I know for everything other than Chevy you usually have to get some sort of adapter for the linkage to hook up an Edelbrock. Here is a pic of my carb and linkage, how similar is that to yours?

Re: Holley carb to Edelbrock carb?

Suprisingly the linkages look very similar. Looking at your picture it doesn't look like you will need any kind of adapter for the kickdown linkage.
I recomend a 1 inch carb spacer too, it seemed to help a bit with my truck, but if you do this you will need some kind of low profile air cleaner assembly, otherwise it hits the hood and will make a nice circle in the form of your filter holder on the underside of your hood.

That is good to hear! I got my carb from Summit today, so as soon as I have some free time I am going to get it installed, hopefully the linkage will bolt right up.

Re: Holley carb to Edelbrock carb?

Well, I got the carb put on, it bolted right up with no modifications! Man, the truck runs 1000 times better than it did with that POS Holley, and I haven't even tuned the carb yet! Thanks for the help...

Here is a pic of my International and my Nissan, the International doesn't look too pretty now since I just started to tear her apart to do some body work.
