What to do about my Holley two-barrel/hood clearance?

[Mustangs4sho]

hey whats going on?
:idea:
i have a 1968 mustang with a 200 and, im trying to get an opinion on what i need to do with my holley 2300. i am having issues with hood clearance and cannot afford to do to much more to the car at this time. i was wandering if i should scrap the holley two-barrel idea and send all the parts back to summit or, get a new remand carb from somewhere. i really want to improve the horsepower but i dont know if i can afford to get a new hood. is there anything i can get or do to make the carb fit or do i need to get a new single barrel and send the $500 worth of parts back. i really need some help quick because it is my daily driver.

THANK YOU!!!

Several others here have Mustang 2-bbls, have you searched on "hood clearance" or something like that?

I don't know about a Holley 2-bbl, or how many / which adapters you've got, but I mounted my HW-5200 2-bbl on a Stovebolt 2-1 adapter straight to the intake (had to drill offset holes, no biggie). Of course, I've got a Ranchero, so ymmv.

Cut a hole in the hood
When I was thinking about doing 2bbl I milled the bottom of my adapter to get it as low as possible. I never finished the project as I found a rebuilt RBS that I put on so I can't say it worked.

Hello,

my "How to" is here :

well the big thing with the clearance is that the carburator is basically touching the hood; so a drop base air cleaner wouldnt work and i cant cut a whole in the hood my pops would kill me. so im still stuck...is there any type of single barrel that would give me almost the same or a little less ponies than the two-barrel.

You didn't mention which adaptor you are using or how it is installed, but with a 200cid I would think there would be enough hood clearance. I'm pretty sure there are others here that are running 2300 series Holleys with adaptors. Did you remove the stock riser plate that is bolted to the intake before you installed your adaptor? This adaptor from classic inlines seems to be pretty low profile, but again not sure which adaptor you have and how tall it is. Here is link so you can see the adaptor.

It is a trans-dapt i bought it from summit...i bought it in a hurry because the classic inlines site was doing some wierd stuff. and i have the adapter bolted to the log manifold, and the carb sitting on top. the log has not been milled. but the adaptor seems to be very low profile; its no more than 1.5 to two inches tall.

so how much of it is touching the hood? is it just the airlceaner stud or is the airhorn touching the hood?

I ran a 2150 (similar to your setup) for a few weeks, was too much carb for the motor, but used the trans-dapt adapter. I had to take it to a vertical mill at work and shave it down, seems like I took almost 3/4" off, then could use a Edelbrock Proflo (triangle shaped) filter with no problems...

I now run the H/W 5200, it seems to be a better match for my stock motor.

Hope this helps

the airhorn is touching in thinking that i am going to have to mill the head...thanks for all the inputs so far..

Get rid of your 2 to 1 adapter and have the log manifold milled for a flat 2bbl adapter that allows you to use the carb you have. Then you can later add a decent cam and do some porting and have more power from idle to 5000 rpm.

I have been running the Holley two barrel for a couple years one of the best mods I have done. It is a snug fit but should work on your set up. My adapter is very close to the one listed one Classic Inlines I'm not sure what you got from summit.

Is there anyway you could get us a couple of pictures?

Are you mounting the adapter straight to the head? Meaning have you removed the water cooled spacer that normally sat between the head and carb?

This is what I had to do, I a Procharger Standard profile carb Hat Blow-Thru 4150 off of ebay.

well despite all the researching i did to make this work...my dad wants to scrap the two barrel idea and go with a carter 1-barrel replacement. but anyway thank you all for your inputs...i am not letting this project whoop me but, since it is my daily driver, i plan on saving it for a better day..lol

thanks
will

Since it's a daily driver and your in a hurry to get it going, put the stock 1V carb back on it for now, then go looking for a spare cylinder head. Don't look for them at your local bone yard, as they will want to much money. Instead check with your local Mustang restoration shops, clubs, or even your local machine shops. If someone just did a V-8 swap, there's a good chance you can get a used head at very reasonable price (maybe free). As time and money permit, mill the head for a direct mount carb, install larger valves, and do as much porting as possible. When that's done, save up for a cam and dual roller chain. Once you have all the parts, swap the cam and head at your convenience.
