These Anti Reversion or Shear Plates for 2" bore base plate carburetors (1050 cfm and 1150 cfm Dominator Carburetors are typically 2" bore) are the only way to fight reversion problems. Reversion problem symptoms are:
1. Poor throttle response
2. Poor cylinder to cylinder control of fuel
3. Difficulty in properly jetting engine
4. Lazy shift recovery and acceleration
These plates simply bolt on between your carburetor and intake manifold and are only 1/2" thick at the deck and the reversion ledges extend down into the intake area a further 1/2".
2" bore Anti Reversion plates: $85.00 each (Gaskets included).
