Holley Carb Help

ok so my dad gave me one of his Holley carbs that he used to have on his 396 race Blazer to put on my 454 build. i looked on the airhorn were i have been told the model number is located. on the front driver side, or the right side if you look at it from the front there are 2 sets of numbers. on the top is R84018 and below that is 2839. but i have found no information on these numbers online. and i need to get a rebuild kit and a new set of jets to tune it down because it will be running wayyyy to rich for my almost stock big block. a

All the 840xx numbers I see are for that dreadful 4010/4011 series, but I do not show a 84018.

Does the carb look something like:


If so, Holley quit making them, the same type carb (like the one shown above) is now sold by Summit under their name.

BTW, the "2839" is a date code. Built in October of 1969/1979/1989/1999.

yup, thats exactly what my carb looks like. i really cant complain about it because my dad gave it to me, and since i only had a 600CFM Edelbrock i figured it was better than nothing at all, lol. so now my question is what is so dreadful about them? i really dont have a choice but to use this carb because i cant afford to go buy a new one or even a used one for that matter. if i buy a rebuild kit for the Summit carb will all the parts still fit in my old Holley?

IMO they are a pain to tune, the one I had would cause a severe bog every time I ran at the track after the drive to the drag strip- only did it once per race track visit, every first run when it as the hottest.

To do much in the way of changing accelerator shooter size, the entire booster cluster has to be replaced.

It may be fine for your use, it's worth a try anyway.

Post a pic of the carb and list numbers (closeup). Summit carbs are not Holley carbs. Parts don't interchange. Should be able to Identify by looking at the carb and numbers.

According to Holley a R84018 is a 750cfm 4010 carb

Summit square bore left, Holley spread bore right:


I see a difference in the location of the needle valve location and angle of the fuel inlet in the top casting, and the mounting angle of the secondary vacuum chamber (and possibly the diaphragm) is different, but the screw locations look similar so the gaskets may interchange.

I seriously doubt Summit tooled up a different needle and seat, power valve, jets, accelerator pump cams and diaphragms, secondary springs, etc. just to be different from Holley- so as for "Summit carbs are not Holley carbs. Parts don't interchange", I'd really want to take a closer look before believing that.

BTW, the reason the List 84018 carb does not show up in the list I use, is because it is a marine carb.

The only photo I found happened to be a spread bore- I know you have a 4010 Holley 750 square bore- similar to the one I showed by Summit.

The only point in it all, was to say that if need be, tuning parts for a Holley 4160-type carb will work perfectly well on your 4010 carb- you do not need to look for anything special in that regard.

In that there are still kits around (providing they are actually on the shelf somewhere) there's no need for using a Summit kit or parts- but if a Holley™ kit isn't available, I think a Summit carb kit would have the right gaskets.

It will work fine on a car as opposed to a boat. The marine part of it usually has to do w/how the carb vents are configured.

If it was me, when it was apart I would check the size of the jets, shooter, the secondary spring color, power valve rating, etc. and compare them to an automotive application 750 CFM 4010 square bore carb just to be certain the jetting hasn't been changed too much.

Not because it's a marine carb, necessarily- but because it was tuned for an engine that is far from what you're going to use it on.

If you find the tune far from what it would have come with originally, I would put it back to stock as a baseline, before tuning it for your engine.

Ball Park Tune:

Something around a 73-75 primary jet, 75 secondary jet, 65 power valve, 31 squirter.

Maybe a silver secondary spring and a white accelerator pump cam to start with.

Sorry, but Summit parts are not the quality of the Original Holley parts is what I am meaning. I wouldn't run Summit parts in my Holley's but maybe run Holley parts in a Summit carb. Chinese parts in an American carb?

PS Holley 4010 carb were originally made for autos and used for marine use later.

That's good you found the kit and quality is never cheap. I like Holley original kits as you mentioned, the Chinese parts for carbs leave something left out in quality. Not a fan of the Summit carbs would rather find a real Holley on ebay if I had to, if you know what I mean. Just trying to help. cobalt327 is correct in telling you to start with the original jets and nozzle sizes as a baseline and then tune from there. I'm sure that's what your dad did, as that's the way we did things back then. The Holley 4010 was a common carb to use on 396 and 427 Chevs on the street in days gone by.
Good luck with your build.
