Naturally aspirated Ford 2.3L

There are decades and decades of data collected on carb jetting. Weber, Delorto, Holly, Carter, SU and Solex , Mikuni and even Rochester. Large volumes of data. Mazda racing books, Datsun racing books, Ford racing books, the carb companys publish data themselves. What scares me is the little electrons I can't see (and Euro Bosch injection). I'll bet there are a couple dozen blown up Honda motors in this little town from kids trying to turbo them and some tuner adding a chip to the stock ECU.

Pete is right tho, those sumbitches have gotten very pricey to buy new....yikes.

doesn't an n/a 2.3 use a four barrel intake manifold ?

you could use an adaptor and run a 500cm holley 2 barrel carb

Carbs are freakin' expensive unless they were gifted to you in perfect tune or they came with a small bucket of jets and bleeds and emulsion tubes and stuff.

Hooey. A few factors and I can get him pretty good.

Its when people get clever that it gets 'spensive.

Like most other things don't be a Clever Trevor.
Pretty good is pretty good.

Yep... and leaving it the way Ford made it is the least clever way to do things, so we're already getting clever.. how deep is the rabbit hole gonna go?

I should look at what exactly I have...
It is a 2 barrel carb, I believe its the Esslinger adapter to a Holley 2 barrel.
The block with high compression pistons was not in the pile of stuff dropped off.

This video comes to mind...

Anyhow, I'll just add it to my slightly growing pile of stuff that comes with the Merkur when I try to sell it again and figure something else out later...

Gawddam Grant you're like a American 21 year old girl sometimes "I want this. Its pretty. I want that. Its shiny!! Oh wait i want , Iwant, I want.

Put the fucking car back together, get a 4.3 in it and have some fun.

Look Sean built a good one-=-all purdy.. and Tom Buress who when his VW junk doesn't break is fast like fast..
When he drove Seans he called and was blabbering away 100mph which is unusual for him and say WHOOOOOOOOA man golly fuck-me it works so good..

And he said Sean had to cuff him across the chops to get him to listen and he said "Its stock engine. Stock clutch, 4.3 diff and an intercooler, that's it"

You have the damn car, you have enough to put it back together--or people will help=---- you don't need to spend money yoy don't have, and get a bazzillion HP.
4.3 and have fun.

And stop being distracted by the latest shiny bauble.

put it together and run it
n/a with a holley or turbo with efi

that is up to you

build the better head later
i have driven an Esslinger powered mustang svo well worth the work.

put it back together and drive it

Unless you mean carburetor, singular, meaning probably a Holley 2-barrel setup made for cheap circle track classes, in which case jets are cheap which is fine because you can't tune dick-all on a Holley anyway, it either runs well or it runs like ass and you have to get very creative to de-assify the tuning. EFI you reconnect the wires you cut when you took it out and you go drive it.

The 2 bbl 500 cfm Holley is pretty easy to 'de-assify'. (I'll add that to my technical lexicon, thank you!). Drill out the air inlets a bit, and then hang wires down into the openings to tune the air bleeds. I used window curtain hanger hooks with the sharp ends ground down to various diameters to stick down into the drilled out air tubes to tune the air; the j-shaped hook part hooked up over the top edge of the air horns nicely. Then tune the fuel jets like regular. You can change the accelerator pumps. Credit John Bell for this idea BTW.

Ran almost as good as twin DCOE 45's; the 45's had 300-400 rpm better more usable low end; probably due to better throat sizing to the engine (1.9L Opel with the knarliest cam Isky made) and better transition-off-idle . Poorer idle and gas mileage too but super driveable once you got the hang of it. Match to a 2.3L should be better. I probably have it still lying about if a pix is desired.

I sold some of my arms to a circle track guy, his high comp race 2.5 on a carb makes 283hp, and revs to 9k. Multiple seasons on a build.


I bet with some decent pistons, a bit or porting, and a carb it would easily make 200. Better than a stock turbo? probably not, BUT it is now G2 legal...... That was the reason I was considering that rabbit hole. Grant, LA/LB computer and a Volvo intercooler is more power than the car needs, and dead reliable on pump gas.

The hell you can't.


You guys make carbs sound so terrible... They're easy, as long as you stay away from that Quadrajet/Carter AFB junk. A 2/4 barrel carb based off of the Holley double-pumer design is very easy to tune and will run great. You'll need a jet kit, and you'll want to consult with a good carb builder/tuner(Patrick at ProSystems is one of the best) to figure out a good starting point for accellerator pump(s), cam(s), boosters, etc. We've bought a few ProSystems carbs that came out of the box and ran nearly perfect on the engine dyno(Perfect a/f ratios, awesome power, etc) on 800+hp naturally-aspirated motors.

Call a reputable carb builder, tell them what you plan on doing(including engine/cam specs, etc), and let them tell you what you need. It'll basically be a GOOD metering block, and changing a few things on the main-body, bowl, etc.

Me personally...I'd want to run a good ITB setup with Megasquirt or similar and Alpha-N that utilizes barometric correction to automatically adjust for DA changes. This is assuming it's a high-winding motor with large cams.

Also, is e85 legal in RA and SCCA classes such as G2, G5, and Open Light?

what is wrong with an afb?

one of the easiest carbs to tune out there.

but for a 2.3 a 500cc holley is the way to go, 10000+ stock car racers cant be wrong
easy to tune parts at every good auto parts place, books with pictures and the list goes on

the holley works very well on road and desert racers

make sure to use a center float bowl
all sort of tuning options

i do favor side webers or fuel injection but for the cash the holley is hard to beat

Ever try to rebuild one?

The holley is super easy to tune and very easy to service on a time constraint.
