Carb upgrades weren't part of
KISSArmy's brief, but hey, you asked.

To All interested:
.....IF you are capable of navigating the labyrinth of support structures for a 1946, ....., have a go at it.
Hey Kissangle, have we scared you away? Overwhelmed you? Let us know how you are doing.
Adios, David
So I started another post with the 65 photos required to explain how the 1946C Holley 1-bbl works. Its emission system may have 85 basic part numbers, but two really great people on the Fox forum have had a go explaining the parts from my show and tell. Its okay, its easier than Mosaic Law...you can use pictures instead of five meaty books and a Talmadic cross reference. And I'll give it to you for
ANickel...if you follow this link...

"The problem is the 1940 part number has two different kinds of carb,
one is a small 1100 replacement,
the other a larger 1101 replacement.
The venturi increase on Ak Millers development six allowed a 50% boost at the rear wheels. Thats 50 hp potential with the bigger 1101 1.29" ventur carb. "
The fact is:
I think you ought to read the article again. Ak Miller only claimed about a 5hp increase from going from the Autolite 1100, to the Autolite 1101[/quote]
Reread it as requested. I was wrong. Should have put 61% increase "allowed" by the Autolite1101.

The behavior of the car at this point was every bit as good as it was in its stock form. We had increased horsepower from 65 to 100 at the rear wheels, yet had lost none of the economy or smoothness of operation inherent in this particular car. In fact, the first comment by people driving it is. "It just has to be an eight-it's too smooth." With a 0-60 time that will give its big brother a hard row to hoe, one can only say that changing of the car's personality had been well worth the expense and effort. After all, getting the gas mileage this little bear gets, we can save money we spent on the performance goodies in short order.
Then Ak added the 260 degree 408 thou lift cam for 105 hp, another b5 hp boost still allowed with the use of the trsty 240 big Six Autolite 1101. So it allowed a 61% peformance boost via a 40% increase in air flow. It did 0-60 in 10.2 seconds with the 100 rwhp, and 0-60 in 9.1 seconds with 115 rwhp from the 260 cam and two 245 cfm (490 cfm) HD6 Jag 3.4 carbs.
An engine is a package. It started off with 65 rear wheel horspower with the Autolite 1100, which in California, only had a a 150 cfm carb with a 1.10" venturi and just a 1.4375" throttle. then, still with the stock 1.3" log head hole with it adaptor radiused to clear the 1.6875" throttle, the 1.29" Autolite 1101 flowing 210 cfm, an extra 40%.
That "allowed" 100 horsepower to flow through it and to the resr wheels. In flywheel terms, 65 rwhp is 82 hp, 100 or 105 rwhp is 126 to 133 hp. In net hp increase at the flywheel, thats 44 to 51 hp.
Of course, when I posted that, I checked my data. Falcon sixes are practically my life, but I
do make mistakes. Like anyone who strains out flees and still ends up swallowing the cammel.
