I see a lot of posts about using the 4100 carb. and if it is big enough for a 289-302. 4100's came in two sizes the 1.08 about 490 cfm and the 1.12 about 590 cfm and was used on 352 and 390's. A 4100 1.12 590 cfm is a nice carb for the modified 289 or 302 and the 351W. looks stock but has more hi-rpm potential on a modified engine.Have had very good luck with these carbs when re-built by Pony -Carbs. Cost is about the same as buying a after market carb but you can use stock linkage and other components. Just my observations but I like the Autolite 4100 Gary

I 2nd the 4100's from Pony Carbs. The one on my 289 went 140,000 miles then was redone 50,000 miles ago. I just got back from visiting them in NY and was getting 18-20 MPG @ 80 MPH. This new engine has a cam, ported & polished, tri-y's, Granada 3 spd manual O/D and the 4V. I have gotten as much as 22 MPG at highway speeds and about 15 around town (and I'm a firm believer that if there are 4 holes in the carb use all 4!!).

This months issue in Mustangs and Fords had a nice article about the 4100 and 4300 series carbs. I like the Edlebrock Pro Performer series. Nice easy carbs to work with. Just my opinion.
