Question about Ford Mustang

1 Answer

I'm in need of changing the 2 barrel carburetor on my 1973 Ford Mustang Mach 1. I understand that if i want to go to a 4 barrel carburetor I will need to change the intake (duh) and the heads. Is this correct? If I stay with the 2 barrel what brand and size should I get for the 351C?

To change to a 4 bbl u wil need to change the intake manifold, as for the heads only if u are going to preformance. Changing diffeent 2 bbls will not be of any advantage to you.

What is involved in a carburetor switch from a 2 barrel to a 4 barrel?

You need to buy a new intake manifold and buy the propper 4 barrel carbruetor.
Try to save yourself some money by buying a carb and intake performance kit from Edelbrock or other local parts stores...

I hope this helps...

2004 ford mustang mach 1 brake lights dont work dont have manual to change the fuse

I don't believe there is a separate fuse for the high-mount brake light. Never was on older cars, that brake light is just spliced into the rear brake lights. Have you checked the bulb?

I'm trying to change the intake manifold and carbuetor on my 1973 Mustang Mach 1 from a 2 barrel setup to a four barrel setup. I purchased a Edelborck Performer 2750 351 2V which should allowed the change....

As best as I can tell from the Edlebrock website and the information you included, you have the wrong intake. The intake you purchased is for "C" or Cleavland engine or even a "M"; when what you have appears to be a "W" Windsor engine.

I screwed up and did not label the wires when I took off the alternator on mt 1973 Mustang Mach 1 351C. I know where the orange wire goes, but the others(s) I'm clueless. Thanks

Red goes to the threade post,main output marked"batt".Orange and blue go to the post marked "feild",closest to the rear bearing.The white and black go to the post marked"sta" or stator.If there is a ground or all black wire it goes to one of the posts on the back of the alt that has no plastic insulater.Let me know if you need more help.

I need to replace the carburetor on my 1973 Mustang Mach 1. It has a 351C 2-barrel and it is leaking. What size and type and model should I get? Thanks! I'm restoring it so I know I'll have more questions.

The tag number is what you would use to get a refresh kit from an auto parts store. As for an NOS unit - good luck. They haven't made those in nearly 30 years. If you want it profesionally redone (like for a restoration) you might contact Pony Carbs. Otherwise, just clean it up, put a kit in it and go.

Good luck and hope this helps. The carb kit from localauto parts retailer would probably run you less than $30.

I need to replace the 2 barrel carburetor on my 1973 Mustang Mach 1. What size (cfm) and which brand would work best? Thanks!

If this is the stock 302 cu. inch V-8, the original carburetor will be a Motorcraft 550 CFM carb. If you would like an upgrade I wouldn't go up on the cfm's unless you do a intake manifold change to a competion intake such as a Edelbrock competition intake or other modifications (increased compression ratio, larger valves, higher lift cam etc.) that would allow increased flow.
