carb options

[Anonymous]

i'm having some linkage problems with my Holleyt 1940 carb. I have a '68 200ci in a 66 mustang. the head may actually be from 69 i can't remember.

i don't know the full terminology to explain the carb problem, i'll try to work that out this weekend and post when i get stuck. but before i do that i was wondering what carb options i have. the engine is rebuilt stock, could i put a 2bbl holley 2300(?) in there. would it be worth it with a stock motor? where can i get the adaptor for it?

thanks everyone. i'll be working on the 1940 this weekend so you may hear from me again soon.

The Holley #1940 is a universal replacement carb from FoMoCo, used for many different models and years with these engines. Although I have never rebuilt one I'm told that they are similar to the later Model Holley #1946- the last OEM carb used on the 3.3s (aka 200). A rebuild kit shouldn't be too expensive and directions are easy to follow. Plan ahead, take your time and work in a well lit, clean, uncluttered area. Be clean and exact.

You can mount a Holley 2300 2 barrel on your '66 Mustang, but know that hood clearance is tight. Adaptors can be had from Clifford and other retailers. The adaptor stands about 2". Well set up and tuned to your engine, you will notice a nice improvement- nothing earth shaking, but an improvement.

Another option you might want to consider is to find a rebuilt Carter YF. It should be a bolt on to your head, and likely an improvement over the Holley #1940. It is a cable actuated linkage thought. There will be no clearance problems.

FoMoCo used several different head castings in the C9XX ('69) years. You will need to identify which head you have to order the correct adaptor. C9DE- C, F, J, & K all have a 1.5" carb bore and narrow carb stud spacing, as do all earlier heads. The C9DE-M casting, and all later heads have a 1.75" carb hole and wider spaced carb studs. Look for casting #s on top of the intake log, behind the carb pad.

Good luck.
