I will cast the tie breaking vote. 351C has small block bolt pattern. I have
one and even the bell housing from my 300 I6 will work on it. Remember, there
is two types of small block bell housings. One for ten inch flywheels and one
for eleven inch. Eleven inch locates the starter further out but bolt
patterns are the same.

John, the 4100 is not a spread bore. The size of the primary and secondary
venturi are the same. No matter though it is still an excellent carburetor.
There is an article in the January 1996 issue of Mustang Monthly that gives
reference and maintenance information. If you would like I can fax a copy to
you (or anyone else for that matter) if you are interested. Also go to the
Pony Carburetors web site. They have some info there on this carb.

http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.cybervillage.com/ponycarburetor

FYI there are two sizes of this carburetor. There is a casting number on the
front bowl under the accelerator rod. It should read either 1.08 or 1.12. The
1.08 is rated at 480 CFM and the 1.12 is 600 CFM. The 480 CFM are getting
rare so finding one may be difficult.

For those of you driving around with inaccurate speedometers due to larger
tires or rear end swaps I found this tidbit in 4X4 Power Magazine you may be
interested in.

To determine what number of teeth your speedo driven gear should be to make
your speedo correct do the following:

1. Find out far off your speedo is. They recomend counting mile markers with
odo.
2. Calculate percentage of error using this formula.
percentage of error =miles shown driven on odo - miles actually driven
/ miles
actually driven
3. Find the number of teeth required by using this formula.
Number of teeth required=old tooth count X percentage of error + old
tooth count

Thats It. Somebody let me know if they use it and how it works.

Brett,

Are you sure you need a cat? A friend of mine had a 86 F-250 with a 460 and
even with CA emissions it came W/O a catcon. It even ran on regular gas
when it was sold here and didn't have a placard either on the instrument
cluster or on the fuel filler doors that said "Unleaded Fuel Only". If your
truck is missing the "UFO" messages then it probably came without a catcon.
Maybe they were looking in the book for an F150 which would have come with
a cat. Also, if your GVWR is over 8500 I can almost guarantee that it
didn't come with a cat since I believe Ford trucks with this engine and
weight rating didn't start using catcons until the engine recieved EFI in
1988.

Maybe you need to find a more lax testing facility. I've been to more than
one that all they did was clip onto the #1 plug wire and stick a probe in
the tailpipe. No ckecking for catcons, or EGR, or PCV etc... If it passes
the sniffer it passes...

Good luck with the smog nazis!
