Holley New Upgrades including annular discharge nozzles

[wsa111]

Summit now offers a new fuel filter which replaces the existing fuel inlet fitting which is hard to get a 1" wrench on to tighten, and at the same time adapts to a AN fitting. The filter has 4 times the capicity of the old filter under the fuel inlet.
With this filter you can get a wrench on the hex fitting with full access.

For those who want to keep their holley 4412, Sean Murphy Induction can install annular discharge nozzles in your carb. The cost is about $75.00 for a 4412-500 carb.

I don't have any comparson data at this time comparing this to the autolite carb.

Hope this lets you guys know whats available for the present holley users.

Looks good. The annular discharge nozzles should also work on the 7448-2300 350cfm, right?

I am pretty sure the fuel filter will not because the inlet is a different size if I remember correctly.

Marco, the annular nozzles are too large for the 7448-350.
Since you have a 200 also you would be better with a 4412-500 with the annular nozzles, but leave the venturi stock diameter 1 3/8" rather than enlarge the venturi to 1 7/16".
If you have a float bowl with the center hung float the 7/8 inlet thread will accept the summit filter assy.

Another option, get a pony carb from Mike at classic inlines, Billl
