Want more power for longer??

The Original and Inventors of the Anti Reversion plates. 

You need one of these USA made Carby Spacer KITS from the Originators at Reher Morrison. Designed by Darin Morgan. 

This listing is for the KIT: a Single Anti-reversion 1/2 plate and the matching 1" Tapered Spacer/adaptor plate.

Overall a 1 1/2" lift of the Carby. * See our listing of the 1/2" Anti reversion plate if you have clearance issues. 223146125317

This kit suits 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 and tapered spacer. Not a Gimmick. 

**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!)
