Want more power for longer??
The Original and Inventors of the Anti Reversion plates.
You need one of these USA made Carby Spacers from the Originators at Reher Morrison. Designed by Darin Morgan.
This listing is for the Single Anti-reversion 1/2 plate for a "normal" square bore 4150 type Carby (Vac secondary, Double pumper etc). The common type carby plate for the majority of Muscle cars. This is a highly effective CNC machined Billet Alloy Anti Reversion spacer plate.
There is also a 1" tapered spacer plate that goes with this anti reversion plate that is on another listing. We have separated
the 2 as some people have under bonnet clearance issues and only want the 1/2 plate.
**Note this is not for a the larger Dominator Carby 4500. They are on another listing.
Reher-Morrison’s CNC anti-reversion plates broaden the power curve of your engine, as they improve carburetor signal, pull more fuel and increase power in most applications.
Other benefits include increased throttle response and faster recovery after gear changes or after coming off the throttle stop! These ½” thick aluminum plates are available with 1.750″ diameter holes for 4150 style carburetors.
Larger Dominator Carbs are 2.050″ or 2.150″ diameter holes for 4500 Dominator style carburetors.
We have 1″ thick spacers CNC machined to match the reversion plates and provide even greater performance improvement!
(A typical 555ci BBC would see an 8-10 Hp improvement on the average!)
