Slant Six Forum :: is this 800 cfm carb ?

1412 is Edelbrock's stock code for a Performer/AFB Non-EGR Manual Choke 800 cfm carb.

Do we get a commission for being a walking Carb ID manual?

Yes, the carb is mechanical weighted secondary so not the best choice for the small engine, most heavy duty slant guys are running a 650 cfm vacc secondary carb. I run a 600 cfm vacc secondary with annulars (so more like 575 cfm at WOT all 4 bores for excellent signal at all throttle positions).

I'm just putting the gas to ya'!

(i.e. getting you ready for that competitive ribbing guys give each other in the pit).

well the seller said it work very well.
I wonder if anyone has ever run one..looks like I will

It's going to run like a big 2bbl.

I doubt you'll get the secondary more than cracked just before the rods pop out of the block.

Sell it to some big block guy and put a smaller carb on. The other option would be to install annular boosters from a much smaller carb in the primary. The secondary might open a bit. Likely not much. The air door on the Carter/Edelbrock will stay shut until enough air is demanded to open it.

I'd get a smaller one. Most slants respond well to 500 CFM AFB's. 600's will work. The only difference is the booster in the primary. If you have a rip-snorting slant, a 600 might be a good choice. If your feeding it through a hose, just make sure the tune is good, and let 'er rip. Won't make much difference what you stack on top. Doc ran a 750 Edelbrock in a pinch, and it did fine as long as he hit the hose at the line.

I get right around 20 MPG with the Hooptie running a 500 Carter AFB. When I run it down the street. I picked up 3/10ths on the track running as a 500 on base jetting, over running it as a 600 on base jetting. Smaller primaries can work well with these carbs.

Then you will kill the engine. Your vacuum will be nothing when the secondary thwacks open. The car will bog at best, and more likely just snuff out.

That carburetor is a pegboard ornament, not a useful air/fuel delivery option for a slant six.

Post subject:	Sounds like.
Quote: $395 new on ebay... Then sell it and use the proceeds to find a smaller carb (500 cfm AVS comes to mind as the 1st choice, then a 600 after that.) Overcarbing an engine will do exactly as Ceej talked about, also the idle mix would have to be tuned back to keep it from being overly rich at all times with the adjustment over compensating due to the size of the carb. This will get worse when compounded with a high duration high overlap camshaft where the vacc. reading is already on the low side (and could live in the power valve area causing the engine to flood or scrub the rings after cylinder washdown. -D.Idiot

have u ever inspect this carb model. I think it has mods. the 2ndarie butterfly is open a little, like someone bent the front of the butterflys so it runs preopen exposing fuel vents? will try and post a pic the seller had this unit in a truck and w/headers...I bought both in an obscure advert. sold the headers

Author:	USAJon [ Wed Apr 10, 2013 7:47 am ]
Post subject:
just inspected the secondaries are progressive the primarys have to open 1/4 b4 the secondaries start 2open the weighted butterfly above the secondaries work with vacumn of the intake and are bent so to b 3/16's inch open exposing a fuel vent. this all looks stock.

It affects the engi in many ways that stroke. I am step by step exploring it because I want to eat a RED for lunch with my Slant 6 FED. I discovered when doing motors for my pals 6 cyk Ford altered that you have to treat a six like it was an 8 carb wise. All the dynamics are there so his 300 Ford was carbed as though it was a 400 Cu in. the iprovements were significant. (AKA beyond I think , or it feels good , more into man look at the drop in ET!) We ran a 800cfm on it.
