Hey guys just wanted some input, got a used carb(heard it run) and going to slap it on tomorrow. Read some threads here, ive got the adaptor plate to fit the carb to stock manifold, throttle plate adaptor and linkage adaptor. I thought there was a kickdown adaptor but all I can see is part #8011 extension rod. Ive also read about these carbs flooding due to high fuel pressure, what does the 460 run at?

Going to grab a universal fuel line kit tomorrow, and want to make sure ive got everything, thanks

 

I'm running an Edelbrock on my 460. I've never had any trouble from the fuel pressure being too high. It does try to vapor lock in the summer, though. I've got my kickdown hooked up, but I honestly can't remember exactly how. I don't remember if it's a part out of the kit or if it just hooked to the linkage on the carb.

 

My Bronco had a 750 Brock when I bought it. Never had a problem with fuel pressure, but it was too much carb for the slightly modded 351. Bought a holley 600 and replaced it . Runs better and gets 1.5 more mpg. But if I read OP correct he is bolting to original intake with an adapter. If it is 4bbl intake thats okay. Wont realize optimum performance if you are adapting 4 bbl to a 2 bbl intake. Might even not run as well as with 2 bbl.

 

I can tell you that if you plan to just slap it on there and go, youre not going to get the full benefit of anything. Adapter plates have never been something that I've been in love with, but they do work; it just feels unnatural to me. If that's what you're going to work with, it may not be a terrible idea to at least start saving up for a proper manifold.

Carbs have to be tuned to each engine, from idle circuit to primary and secondary metering systems; acceleration pump shot, choke rate; needle type, jet type, spring rate and all that good stuff WILL be wrong for your engine.

If you want to have all of the stuff you need for your engine, you should include a fuel air ratio meter and Edelbrock's tuning kit for that carb, and you should read and understand the manual as it's full of really good information on how a carb works.

A fuel air ratio meter is the BEST tool for adjusting carbs that's on the market, if youre going to move away from a stock unit. The big down side to having one is that you'll realize how terrible carbs are for delivering the wrong mixture at all RPMs.

 

you will need this part as well. http://www.summitracing.com/parts/edl-1483/overview/

 

2 Edelbrocks and both dumped fuel into the pan. One got a preasure reg and the other just got tossed for a Quick Fuel.

I'd sniff the oil frequently if I were you.

 

Just bolt it on and see how she runs.

I have an Edelbrock 650 on my 460 and it runs great without any kind of fuel pressure regulator. I think the 750 is a better size for the 460.

They are a nice simple carb and work just fine on the stock cast iron intake.

I went with a cable kit from Lokar for the kick-down which made for simple install and easy to adjust.

Depending on how old the carb is, you may want to freshen it up with a rebuild kit which only runs about $30.00. That way you can go through it and know that everything is good.

Good luck with the install.

 

Get a "Fuel pressure / vacuum" tester gage, and use a tee and check your fuel pressure before the carb.
My old 351M stock fuel pump made exactly 7 psi, exactly on spec according to Chilton's.
I don't recall what 460s specified, but 7 is too much for an Edelbrock carb, so I added a Holley 12-803 FPR and set using same gage at 5.5 psi.

A new Edelbrock that hasn't been monkeyed with will likely do OK right out of the box even on a 460 ...
... if supplied with less than 6 psi and the included instructions are simple for making minor tuning adjustments.
