I've got an opportunity to purchase this carb. It came from a 72
Lincoln Mk3 with the 429.

I can't find any definitive information on the 'net about the venturi
size, CFM, etc (only a site stating the "bore" is 1.25). Does anyone
have a book with this data offhand or any first hand experience?

Let me know when you can, thanks!

...and also how well suited this carb might be for a 289....

Hearsay says 4300 carbs are temperamental and hard to tune.
This is a 4300A I presume, and is a square bore...

I had a 4300D spread-bore on my 72 Mach I ... too many
years ago.... the lack of info on the web implies they
are rare or not that popular. I have the 72 Shop Manual
and it shows the 4300A and D, but not much info nor any specs

My $.02 says almost any other carb would make a better choice
than the 4300 for a 289.....

According to the *Ford Carburator Guide, 4th Edition* (by Pony Carbs):
In '72 the 4300 came on 429 and 460 V8's with 1.25 bore and 600CFM. The
model # you listed is in fact for the 72 Lincoln, but the book only lists
the 460 engine size, not the 429.

Production years for the 4300 were only from '67 thru '74. The 67 model was
one size rated at 441 CFM, which they say was about right for the 289
engine, and undersized for 390's and big blocks. In 68 they came out with
the 600 CFM for big blocks. The small bore version was discontinued in
1970. The 4300D spread bore (that Walt mentioned) was rated at 715 cfm
(1971 thru 74).

The 4300 model was Ford's answer to state and federal pressure for better
fuel economy, and with it came decreased performance compared to the 4100.
The 4100 is revered by some as the best 4 barrel carb ever made (I'm sure
some on this list would debate that claim though). I love my 4100
1.08, but it's the only 4 barrel carb I have ever owned, so I have no point
of comparison.

Hope this helps.

Tremendously, thanks.
