I am converting my 70 Mach 351W from 2V to 4V. Since 4V was not offered in 70 I am following the 69 spec's. What carb was on a 69 351W 4V? Is it the 4100 or 4300? Since I am going off stock would a Holley 600 perform better that an original? The long block is a 69 4V with all original parts. I found a std bore motor that was sitting for years and tore it down and resealed with all of the original pistons, cam, etc. My Mach is also an original shaker car and will all carb's fit under the unit?
I am a stock guy but want a little more perfomance by going 4V and dual exhaust. I am keeping my original pieces from both to go back to stock if desired.
Thanks,

The 1970 Mustang M code was the 351 4V.. My 69 351 4V , the card is a 4300. Pretty well the same one Ford used up into the 70's.

4300 is not even close to a performance carb. Better just use it for show and get a after market 600cfm. not necessarily Holley Even a 4100 1.12 is better than a 4300. gary

Stay away from the 4300! IMO, it's hard to beat a Edelbrock 600 CFM. These suckers run really smooth on the street! Great carb.

Go with the autolite 4100. Trust me, it is one dang fine carb for all around performance. If you want a carb for pedal to metal, then go with something like a holley, but for all around performance and smooth acceleration and easy maintenance, a 4100 is hard to beat.
However, the '69 351W 4v didn't come with the 4100, so the fuel lines and choke tube won't hook up. NO PROBLEM. Check a local mustang vendor and get the choke tube and fuel pump to carb line for a 351W 2V. It'll hook up perfectly and you won't be disappointed.
If you don't have a 4100 on hand, find a core and exchange with Pony Carbs. I think it would be around $240 exchange.
The tubing will run you approx $38.
Good luck.

If you go with the 4100 which is a great carb, get the $20 rebuild kit, $20 worth of carb dip and do it yourself. $240 to rebuild one of the simplest carbs on that planet is just ridiculous. Wouldn't you rather put that extra $200 towards other stuff you need? Just MHO...

Agreed that the 4100 is not that hard of a carb to overhaul, but if the carb is totally worn out, a kit rebuild probably won't get the job done. Yes, I'd rather spend money elsewhere, but if you've ever experienced tuning problems with a car, not to mention running too lean which can be a big no no, it can be a total pain. I know lots of experienced and knowledgeable people in the mustang hobby that will fork over the $$ and allow Pony to service their carb.
JMO too. Thanks.

Once I got the start off stumble out of this carb I have not had any problems, it is easy on fuel and very lively.It gets old gal up and going without any problem at all. I do use premium gas in this car though so maybe that has a lot to do with problems with this carb. I don't race or drag, I restore for my own plessure.
The 4300 was the carb that came on the car that year and that was what the poster wanted to know.

Thanks for all of the replies. I did not want to start an arguement and I know everyone has their own preference. I am a casual driver with a very clean driver I try to take out every weekend. I do not plan on racing this car so I will look for a 4100 or 4300 if possible. I do like to stay with a stock appearance. Thanks again.
