Ok so I have seen a few of you with aftermarket carbs on your rides…..Did you keep the stock intake, and use an adapter plate or did you replace it with an aftermarket intake. If so what did you use?June 18, 2020 at 6:24 pm #1697562cutlassconvertParticipant
Stock manifold. I used an Edelbrock 1403, elec choke, 500cfm. There is a manual choke version.
No adapter plate needed, bolts up.
I did use an insulator under it to isolate it from the intake manifold heat.
Your stock air cleaner won’t fit, it’s for old form 4bbls and too small for the new std size Edelbrock.
Several ways to go but what I did was use a riser that fit the Edelbrock and went around the outlet on the stock Cutlass 4bbl air cleaner. It has a rubber O ring that seals to the air cleaner. The Edel is lower than the stock carb and the riser works good and plenty of air flow for the Edel, and clears the hood. I’ll attach a pic of the riser, got it at Summit, cheap and nice.
You will need to make a new throttle linkage-easy job with a couple of rod end and straight rod. See pic
If you are going to a later trans the kick down cable needs a bracket at the carb, I made one up from a joist hanger and universal kick down bracket kit. See pic
If using orig trans someone else may have a solution for that.
There is an. older post in here somewhere on the subject above with various options and pics, you need to do a google search on it if you want to find it.June 18, 2020 at 7:08 pm #16980kgfiskeParticipant
I used an Edelbrock aluminum intake manifold with an Edelbrock 1403 ‘performer’ 4 bbl carb. A nice combination. The Edelbrock intake manifolds are still available. Probably the only reason why is because the 215s were used for years on the Landrovers.June 19, 2020 at 8:36 am #16986joe_padavanoParticipant
My E-brock 1403 bolts directly to the stock intake manifold. I had to fabricate linkages for the accelerator and transmission TV rods.June 19, 2020 at 9:22 am #16989oaklyssParticipant
How about duals? I bought some linkage rods and ends and made it work with the stock TV linkageJune 19, 2020 at 12:03 pm #1699262cutlassconvertParticipant
Nice. What is that 2 2bbls?June 20, 2020 at 5:53 pm #17002captiannapalmParticipant
Thanks for all the input. I am not a big fan of Edelbrock…Already purchased my Quick Fuel…..not really wanting to use the adapter plate… hoping for a clean look…June 21, 2020 at 8:07 am #17003joe_padavanoParticipant
The manifold has the small (Rochester) bolt pattern. The E-brock comes with both the Rochester and Holley bolt patterns drilled in the base plate, so it bolts on. The QF apparently only comes with the Holley bolt pattern, so it does not bolt to the stock intake.
