Ok, my thinking was that if vacuum was 18 inches at idle, I should start with what hg spring rating? If my vacuum is 10 what hg spring would I start with?
Using Geoff 2s method, finding the whats needed would be real quick, as there are only five different springs. thanks
Guys, I have very little experience with tuning the Edelbrock carbs and need some understanding. Im taking a used, highly modified 1406 back to stock calibration first and then will proceed to fine tune it for current engine use. Question is, the 1406 calls for metering rod spring to be orange...
Here is a pix of a painted rebuilt Quardrajet carb and here is one that was installed last February. See the paint rubbing off at the air filter horn. As Rishi said, it's paint, it will rub off, scratch off or be dissolved off. There is a reason they did not come factory painted. So, don't get...
Ethanol added fuel is defiantly a lower performing fuel over non ethanol fuel, but to single it out as the cause of your stumble itself would be a stretch. It can cause rubber seals and gasket deterioration in the whole fuel/carb system if the components are not designed to handle the blend. Old...
Ive have a carb guy out of state rebuild several Rochester carbs for me and I am sure he spray bombs the main body. They look good still after two years in service and I run regular 10% ethanol gas thru them. So, I m pretty sure the paint must be somewhat fuel resistant but sure it will...
Im in the same fix as 33 IMP, my carbs have been hanging on the wall since before ethanol was added and wielded together seems the correct term. I got a bowl tore off but damaged the metering block trying to chisel it off. Contacted a close advertised carb rebuilder and even he does not want the...
Thanks all. Several name brands have been mentioned here with a good report and I am checking them out, haven't seen any listed as trouble, do not buy, so maybe my choice will be good.
Guys, I am not talented in fine tuning carbs and was thinking now would be the time to weld in a bung on my 73. Running the exhaust system now. Have a fresh reworked TQ installed on a 440 and hopefully firing it up soon. If you do, what brand/model do you like best. thanks...
Bro, you bout done got all the goody outa that tank. Prolly just what my 73 tank looks like , sept I did not have the see thru holes yours did. Thanks for the visual ......
Awesome, thanks, so the short square inlets were for 73s and the long, more rounder inlets were for the 74s? I think either will work for me...now that I know what I m looking for, will see what prices eBay is offering....thanks...
Guys, just curious to know what was the stock air cleaner that came on my factory 400 , a single or duel "snorkel " unit. I assume all engines that year were blue so would the cleaners been black in color. Can I assume the orange cleaners were on only orange painted motors. Did autos and...
Great info, thanks Guys. Thought I was close to firing her up but, one thing leads to another. After trying to clean up the engine bay , I now am about ready to drop the K member for clean up and rebushing. Sent the brake booster off for rebuild today, gezzz, what a job to remove, and looks...
Guys, trying to determine how to bend my fuel line from pump up towards the carb on a 440. Coming up behind the Alt. is easy but the dizzy really hinders a straight shot....just wondering how the factory did it. Can t seem to fine a pix strumming thru my old magazines...
Thanks for your thoughts Guys. As for the "stock" 440 rebuild, this is my first dabbling at one and I wish to see the base line first. Plus, after many , many years of collecting parts, now is the time to use them up and begin transferring my cars and junk to new caretakers. It s time to start...
This is the stock intake, if I get it to upload, that I am planning to use. I found a brand new , in the box , Eldlebrock carb, that I purchased for another project years ago that has never been installed. The script says its a 750 cfm, manual choke and #9907. How does that compare to a 1407...
