It may be time to try another carb. If I abandon my Autolite 4100, I plan to go with either a Holley or Performer because parts are readily available in the local shops although I'm intrigued with the Road Demon carbs. One of the reasons I chose the 4100 was because a lot of the parts I already had from my two-barrel setup could be reused. For example, the fuel line bolted right up. I've got a .030 over 289 with home-ported '72 302 heads, a CompCams XE256H cam and kit, Hedman 88300 long tube headers and a Weiand Action Plus manifold. The engine is backed by a green-dot C-4 and a 3.00 open rear. One thing I noticed is Edelbrock makes a Ford throttle CABLE linkage adapter, but there's no mention of needing an adapter for rod linkage. Would I need to switch over to a cable thottle or kickdown linkage? The 500 cfm version seems like it would be big enough for a mild street car. Any thoughts either way? Has anyone tried a remanufactured Performer? Any other comments would be greatly appreciated. deadhead

I have a 289 with a performer 600, it may seem like too much carb for me right now, but with some cam upgrades and some new heads it should be ok. for you I would say its fine.I had a 2 barrel 2100 carb before so the performance was like night and day. I cant imagine ever making a change that big again.
I can roast my tyres pretty good now. If you have the rod linkage for your throttle you dont need the cable adaptor. My c4 tranny has a cable kickdown from lower down on the throttle linkage so I had no problems with any of it. I did have issues with the PCV hook up to the carb, needed some hose and some imagination there. Plus the fuel line is routed differently at the moment its just a felxible line and a big clear inline fuel filter. You will need to mess with the clip to get the rod into the throttle arm on the carb. I bought a die and threaded the rod that way i got rid of the clip and now i put a couple of little number 10 nuts on the back to hold it on. Otherwise I have no experience with the holley stuff, but i can tell you that changing rods is very easy on the performer carb, and it hasnt leaked or broken in the month or so I have had it.

I know the struggle you are dealing with and I just purchased a Road Demon 625 for my car. I like this carb and the way it is made also Holley parts interchange with this carb as well.
But as for your application, I would go with a 570 Holley street avenger. This was the other style carb that I was considering and will be easy to install.
I know alot of people like the edelbrocks but I am not one of them, just a personal choice.

In my personal experience (Mildly built-up 302, alum heads w/2.02-1.60 valves, Perf RPM intake & 214/[email protected] .472/.496 lift) going from an Edel perf 600 to a 600 Double pumper Holley brought a tremendous performance increase, roughly the same gas mileage (if I keep my foot off of it !). It is the best carb I ever saw for my set up.

Pierre, just a side note: There is no such thing as Holley 650 'Double-Pumper'.
All 'Double-Pumpers'(Which simply means it is equipped with two metering blocks) have been 750 CFM or larger.
In addition, no 'Double-Pumper' has ever been made with vaccuum secondaries, only mechanical.
Now, there are Holley vaccuum-secondary carbs in 600 CFM and up that are actually 'Dual-Feed' carburetors. These have dual fuel-line inlets,one in front and one in the rear.These are mistakingly called 'Double-Pumpers' all the time.
These dual feeds have only one metering block, in the front of the carb(primaries),and instead of a metering block for the rear(secondaries), they utilize a much-simplified metering plate.------------------

Well then you better tell Holley that they really don't make the # 0-80592S (600cfmDP) or the #0-4777C (650cfmDP) just to name two of them... take a look at: www.holley.com/HiOctn/ProdLine/Products/FMS/FMSC/FMSC.html#Universal Ryan

OOPS 
They (Holley) actually produce 390 CFM double pumper carbs and have since the 70's. ------------------

Boy, I hate to be proved wrong, but I like to learn something new, so I stand corrected.
I believe these carbs were added to Holley's line relatively recently, and that's probably why I am unfamiliar with them, being as I 'm an old geezer and all.
I don't really know everything, I just act like I do.
Thanks for settin' me straight! Kit.------------------

Uh,..... nope Mr. Venom.
They have been around since about 1970-71. I purchased my first double pumper around 1972 or so and it was an R-4776 600 CFM unit.
Used to be the most common missconception was assuming or calling all dual feed Holleys double pumpers. ------------------

They are called doublepumpers because of they have two accelerator "pumps" one on the primary side, and one the secondary side.------------------

 Being new to the Holley world, after reading Cobravenom's post I had to go down to the garage a double check my carb reference and pinch myself to make sure

I have a Edelbrock 1406 on my 66 and put a 750 Edelbrock on my old F250 with a 460. I highly recomend them! Extremely smooth carbs, run fantastic right out of the box. I have nothing against Hollys, but just because it isn't a Holley is no reason to pass.On my 66, I cut the end of the linkage off that atached to the carb, threaded it with a 10/24 thread IIRC, and put a spherical end on it that I bought from McMaster Carr. It was something like $5.00 or less, looks really trick, and is very safe and smooth. I'd post a picture but I don't have one on a host site right now. If you want to see it, email me. Tom

I like the E-brock performer 600 cfm carb. It works well on my 302 and on my 360. I can't tune worth s%^&t, so Holleys and I don't get along. Don't go under a 600 which ever brand you use.------------------

Gee, I guess I should just stay off the subject of carbs. I have been really misinformed!------------------
