While talking to the Holley rep about card size and that the 600 I had on wasn't doing the job, as soon as I mentioned the y-block he said the 465 was what I needed. A direct replacement on 57 and later y's. It's not seen in the speed shop listings and not on the shelf at the local parts stores but it's a very good carb and sized right for stock or a little engine mods as I have on mine. Gary

Really, that was from Holley direct?  very interesting.  Ive talked to the tech at Jegs, and used the holley on line carb selector, and both came up with the avenger 570.  Actually, the carb selector thingy came up with the 390 or the 570, but never the 465.  Looks like I should give them a call, huh?

I like the idea of the 465 due to its being physically smaller, and having a single inlet.  I do wish it had jettable secondaries, but oh well.  Im also concerned that the 465 wont flow enough at top end vs. the 570, but I guess there is no way to know between the 2 other than to try them.....

Gary, what kind of mods do you have on your car?  Did it require some jetting/power valve, etc adjustments?  Thanks!

Hey Ron, I'm running a 272, I had the large valves installed, an rv cam, pertronix with the flamethrower coil, plugs gapped at 40, a 57 intake and the 465. Put it on and right from the box it was good, just a couple miner adjustments on the idle circuit and it's been go ever since. I had a Holley 600 on it, when I wen t to check on the metering block it was dissolving right in my hand, that was the cause of all mt problems. When I contacted Holley they knew what was going on, some bad metallurgy on some of there units. They would exchange it for another and when I mentioned y-block they immediately said 465, they also mentioned the 390 but they thought the 465 might be a little better in my application. Great guys to work with.

Ron:

At the beginning of this thread, you stated that the Holley lacked top end power.  Just a thought.  Are you sure the secondaries were opening?

Here is a link to the Holley site regarding the 0-1848-1 465 CFM carb.

Click on the tech info for hooking up and adjustments . The drawing looks like a 57 Ford accelerator linkage.

Myself, Holleys are not my favorite carb.

Yeah, I saw that and noticed the linkage.  Looks like its time to call Holley....

Gary, the carb was opening all the way on the 390...

The more I read the more it seems that the poor throttle response of the eddy might be more due to the 500 cfm (and weak/poor signal) than it being an eddy/carter style?

Ill post up what Holley has to say once i get a chance to call them.

Thanks!!!

Also, i just noticed that the 465 is a hot air choke vs. electric.  Sorry for being ignorant, but how does that work?  What does it require to work?  Do I have to plumb it to anything or does it just sit there?  Pros/Cons vs. electric?

My 57 intake had a choke tube tap into the hot air crossover already when I got it, a small tube connects that to the choke housing on the carb, as the engine warms up the hot air slowly opens the choke. I'm a manual choke guy myself and I've never messed with the electric ones but this works very well and concidering that it's never driven in cold weather it's not much of an issue. Are you gonna be at the show in Sycamore next weekend, I'm driving down for it. Gary

Gary,

That makes sense, but I have one of the original mummert AL intakes, so no heat passage for the choke tube.  Id have to get the electric choke conversion kit for about $50 or so.  No big deal.

Talked to holley tech.  Soon as he heard 56 ford he said the 465.  He didnt really seem to care/want to hear about cam specs, rear end, etc....just automatically went to that carb.  Not sure if that means its the perfect fit, or that he just didnt want to deal with me!?!?!  Right now, Im inclined to try the 465, hoping it gets me the best of both worlds between the 390 throttle response and the 500 WOT power.  Like most, i have a hard time accepting that bigger isnt always better!

As for the sycamore show, we wont be there.  We are going to AZ for 2 weeks this sunday to visit parents, so.....

Where is St Germain, anyways?  We live about 20 miles south of the WI border, almost due south of lake geneva.  There are some good shows/cruise nights around here....let me know if you ever want to make the trip or want info about car shows, etc.  We have a GREAT car club in northern illinois - lots of activity, no dues, no politics, no elected officials.  Its pretty amazing actually.  About 240 members or so.....let me know if you want to meet up sometime!

**EDIT**  HOLY CRAP!  I just looked on google maps... you are WAAAYYY up there!  That is a long drive to sycamore!  Stay safe!

Ron, or you can get the manual choke kit, you should already have a choke hole in your dash. I think the 465 had everything to offer for the 57 312's and then some. Unless you're going bigger cam or strip application it should do fine. Its 348 miles to Sycamore, but it's all down hill, thats why I put in the front disc brakes. Gary
