The Decker Machine carb???

[TMCarbs]

Maybe a stupid question, BUT is a twin blade dominator 4500 carb doable?

Ok the 1400 Twin Blade is like having a 1250-4500

The 1600 is like a 1350-4500 say like a 2.250 throttle bore

Like Robby said earlier you have the 800 1000 and 1200 they are basically the same dimensions as a 4150 in size on the out side.

Here is the difference 800 is like having a 750 with the bridge booster Down Leg design, and smaller with annular boosters.

1000 with DL bridge around a 1000HP and smaller with annular boosters.

1200 with DL bridge around the same as a 1050HP and smaller with annular boosters.

Here are the bridge boosters the Down Leg and annular

Here are the upper jets that simply screw in with a screw driver

1400 & 1600 are bigger than the others but can be bolted on a 4150 intake, some grinding is necessary on the opening!

I just did a TB-1400 alcohol Twin Blade for local racer Paul Rebis and his 434 SBC that’s in a 70 Nova which he ran for the first time Saturday at orlando Speedworld!

Paul‘s quote “it’s like fuel injection it’s so smooth”

I’d would also like to add I build all the Decker Twin Blades for Summit 1000-1200-1400-1600

How many distinct Twin Blade bodies are there? Which ones require a larger air cleaner base than a standard 4150? What size ac base is needed for the ones that don't use a 4150 base?

How many distinct Twin Blade bodies are there? Which ones require a larger air cleaner base than a standard 4150? What size ac base is needed for the ones that don't use a 4150 base?

The 'smaller' version has 3 main bodies that fit the same baseplate. (cfm from 600-ish to over 1200.) The 'larger' version has 2 main bodies that fit the same baseplate. (cfm from 1200-ish to over 1600.)

Smaller main bodies use the same air cleaner base as a Holley 4150. 5-1/8"
Larger main bodies use the Braswell size. 5-5/8". Dominator adapter rings are readily available.
