Holley replacement

[Bob M.]

What carb will work on my 67-350 original motor? I have a 3810 on there now, it needs replacing. I have the original intake, need help. I don't want to invest in an original.

Bob,

Unless your 3810 has some sort of damage, sending it out for a professional rebuild IMO would be the best $$ spent. The auto choke and calibrations of the 3810 are good for the 350hp engine. I know there are better carburetors on the market now as some may suggest but for me I like to keep things original.

Re: Holley replacement

Thanks for the response. The 3810 has the wrong date for the car, it has a 1970 date. I need guidance for replacing this one that leaks bad, I am giving up on it, to much time and effort spent on fixing it.

Holley make new reproductions of the 3810 carb. It wil be more expenses than rebuilding what you have, but everything is new and it keeps your car looking original. I've used a reproduction Holley 3811 on my 390HP car the last few years and have been very happy with it.

Re: Holley replacement

I had persistent and multiple problems with a old Holley 2818 carb and rebuilt it myself........twice. No help. After that I sent it out to a famous carb restorer whom most people here know. The carb came back looking beautiful, and he charged me a few extra bucks to change the date on the air horn. Only problem was..................300.00 later, the thing was still mucked up with no improvement in drivability. I finally solved one major problem myself after some digging, but the niggling stalling/flooding problems persisted until I eventually took it off and threw it out the seventeenth floor window of my penthouse apartment.

I bought a Quick Fuel (Holley clone) and the car performs like it has electronic fuel injection!

In your case, if you are obsessed with originality, I suggest a brand new Holley, although the difference in quality (and price) of a new Holley and a QF are quite different.

There are many Holley carbs that would be a bolt-on replacement for you. Anything in about the 600 CFM range will work fine. Here are the problems:

1) Most, if not all, of the current Holley replacement carbs (except reproduction carbs) are not designed for use with a divorced-style choke which is what your application uses. So, you have to be OK with the use of an electric choke or manual choke if you use one of these;

2) The fuel inlet location/configuration may be different. This may require fuel inlet line bending or other "re-configuration";

3) The air cleaner mounting surface/size may be different, requiring the use of a non-stock air cleaner.

All-in-all, I think your best bet is a Holley reproduction carburetor. Yes, they're expensive. However, they're a bolt-on, easy installation. And, I'll say something I've said a million times before: NOTHING makes a car run like a NEW carburetor. NOTHING.

Re: Holley replacement

Hi there!!

I have to echo the sentiments that Joe has posted here ---

I have a newer Holley replacement / reproduction 3810 running on my recently acquired small block 300HP '67 coupe ---

This is just an outstanding piece --- unless you are going for maximum judging points --- and if you just want trouble free driving ...get the modern replacement --- it works --- PERIOD.

Re: Holley replacement

Thanks to all for your help. Holley both times I called put me on hold, they said a 40 minute wait to talk to someone, heck of a way to do business if you are trying to buy there product. I called a company called Jeg, they called Holley and Holley said the 804575 would fit my bolt pattern, I looked at that one locally and the bolt pattern isn't close. The parts house said we can put an adaptor plate on it, I said no thanks.

I just can't justify the money for a carb if I'm not having this car judged. I'll keep looking, Holley must make a replacement minus the adaptor plate. They just don't want sell to many carbs if they put you on hold for such a long time.

Thanks to all who have replied to this thread. I haven't given up yet.

Re: Holley replacement

Interesting. I have a '67 327/350 so the 3810 is near/dear to my heart. Not that long ago that 3810 carb was easily available new from many retail outlets including Jegs, Summit, etc under Holley's Muscle Car Restoration carbs series (or something like that). I don't see them anymore except for a couple specialty retailers.

For what it's worth, there are some new ones out on eBay currently...including auction #330549517783. NOT CHEAP!!!

I'd keep trying to contact Holley somehow (email maybe?) and see what they have to say.

I wish you good luck and hope you find a solution.

As I understand it, Specialty Parts is THE source for the reproduction Holley carbs. Holley manufactures these only in "batches" for Specialty Parts. So, any other retailer has to obtain any they sell from Specialty Parts. Whether, or not, Holley intends to continue manufacturing these carbs for Specialty Parts or whether Specialty Parts wants to continue to lay out the cash for whatever Holley's minimum order is, I don't know.

This is not really a case of making a recommendation on the basis of originality issues. It's a recommendation based on functionality issues.

First of all, I believe the carburetor you're referring to is a Holley 80457S. This carburetor should be a simple bolt-on, sort-of. Assuming you have a stock, original manifold, this carburetor should be a direct bolt-on with absolutely no adapter required. However, that's where the bolt-on ends. As I mentioned previously, you will have a carb with an electric choke. That means you'll have to find a 12 volt source to apply current to the choke. Also as I mentioned, you will have to adapt the fuel line to the carburetor. Finally, also as I have mentioned, your stock air cleaner may or may not fit on the 80457S. In addition, the 80457S has a shiny metal finish, so it won't appear like your original carburetor. But, with the considerations I mentioned, it should otherwise function perfectly. You will pay at least $350 for this carburetor.

If you go with the reproduction Holley 3810, it will be an EXACT bolt-on. Everything will fit as-original. No adaptations will be necessary. Everything will fit perfectly. In about 30 minutes you can have the old carb off and the new carb on and ready to run. Yes, it will cost you about twice as much as the 80457S but there will be real value in that extra cost not to mention the fact that, notwithstanding the issue of "date", will make the car more valuable and attractive to buyers should you choose to sell at some point.

One more thought: the reproduction 3810 is currently available and is virtually a perfect and NEW copy of the original carb. That's remarkable. Will it always be available? I highly doubt it. Carpe Diem!

Re: Holley replacement

Joe,

The 80457s was the first one I looked at because that is what Jeg said would work, I found one at a parts house. I took my gasket with me to see if the bolt pattern fit my intake, it didn't, not ever close. That is where they said I needed and adaptor plate, so I kept looking. Advance is trying to help me with my problem. They are ordering in 2 Holley's, one that has 600 cfms and other has 650 cfms. They both are gold which is what I wanted, but I still have to see if the bolt pattern fits my car. Like I said earlier I'm replacing a 3810 with the wrong date, so what ever I do it has to fit my intake, and it is original to the car. I didn't think this would be a problem finding a carb. I will update everyone when I get to see the carbs coming in and what decision I make. Advance said they both will fit my car, we will find out today or tomorrow for sure.

Again, I want to thank everyone that has tried to help me.

Not to burst your bubble Bob, but I'm pretty confident that those Advance carbs are generic replacement carbs. At a minimum you will be dealing with adapting the fuel line, the throttle linkage, and the choke setup. You can get it to work, but it won't be a 30 minute (or less even) job as Joe has already pointed out. Just want to set realistic expectations.

I've also noted that the link that Lief provided is ultimately the same supplier that is behind the eBay auction that I provided the Buy-It-Now auction number for.

I wish those new 3810's were cheaper...I'd buy one for myself if they were.
