Number 1 Stop Products DP-5 PK Throttle Stop T-1030

Up for sale this week is a new never used or installed Number 1 Stop Products DP-5 PK Throttle Stop kit 

that has been in storage for many years.

It was removed from the original packaging for the first time for pictures for this sale.

The DP-5PK Adapter Stop will bolt to a standard Holley (4150) bolt pattern intake or a 

Holley Dominator Carb  (4500) bolt pattern intake. 

With the addition of an optional top, either a standard Holley (4150) carburetor or a Holley Dominator (4500)

 carb can be bolted above the throttle stop. 

The new oval shaped throttle blade increases flow over round throttle blades. 

The total height of 2 inches makes this a bolt in replacement for most adapters presently on the market. 

No hood scoop or throttle linkage change compared to adding a stop on top of your adapter. 

With both adapter tops (optional) you can bolt your stop to either standard Holley (4150) or 

Dominator (4500) style intake and bolt either a standard Holley or a Dominator carb by only changing the

 adapter top.

We had it tested at a local drag racing champions race shop, he said it works as it should. 

Features

Bearings on throttle shafts for long life and repairability.

Seals on bearings to eliminate vacuum leaks.

Heavy duty solenoid with internal spring and rubber boot to keep dust and dirt from fouling mechanism.

Exclusive stop adjustment knob is divided into 10 divisions (makes it easier to use throttle control programs

from your weather computer because computers have trouble with "flats".) 

It also has a marker to let you know what "turn" the stop is set so you never lose track or must measure.
