I have a brand new Edelbrock 1406 carburetor the I would like to install on my 63. I have used these carbs on several vehicles that I have owned (Fords) and they work very well straight from the box. My concern is connecting the TV rod to my Jetaway tranny. Is there a way to mate the TV rod bracket from my AFB to the Edelbrock carb or do I need to get creative? I spent some serious dollars to have my tranny rebuilt and would hate to screw it up over a simple carb swap. Thanks
A Dwell angle meter ( for point adjustments ) will have the expanded RPM meter as part of it
The above should read -- until the RPMs go as high as is possible when adjusting the front carb screw adjustments
The RPMs will increse and then start to decrease as you are making the adjustment
Keep the adjustment where the RPMS stay the highest on the expanded meter
My 1406 on my 64- 429 had to be made richer with metering rods and a jetting change
Required for the pump gas we now are using
This was done in two stages with the direct help from the Edelbrock techs
Your 390 may be a bit different
Give the techs the numbers on the rods and jets you now have
They will tell you what to do next
The proof the jetting is correct is when the plugs are burning a paper bag color
This needs to be be done -- only after all other engine issues have been corected and a complete tune up is done
Then it is time to set up the carb correctly ( jetting and idle mixture ) and --NOT touch it again --for any reason ( or until a new replacement carb is installed again )
Do not --for any reason-- play with the carbs mixture settings at the front of the carb any other time - than the set up at time of a new carb installation
I see people playing with the carb adjustments to often --so had a need to explain that
Changing the carb adjustments any other time will make the car run worse not better unless done on meters or a bung ( air mixture sensor in the exhaust pipe )
If and when your points and timing are on spec these cars run smooth and strong as a rule
If any issues with engine performance that WB the first place to go to be sure those two settings are correct and knowing that do any trouble shooting to resolve any other problem that might exist
You need always to know the basics are in order and then proceed with any other trouble shooting issues you may need to sort out
What are advantages to going to thrse more modern cardureators, what do you accomplish vs the rochester inhave on my car. Im not touching mi e, as i think car is running just fine, just curiuos to the reason
The main reason I believe that folks are going to the modern Edelbrock is a lack of resources. If there were stock carburetors readily available, there would not be a need to go with an Edelbrock.
The Edelbrock does have a bigger primary throttle, so there is a slight increase in bottom end performance.
The Edelbrock is much easier to adjust too.
