Installed a New Holley 50 CC accelerator pump kit yesterday.
A new 50 cc alcohol diaphragm to withstand today's E10 ethanol pump gasoline.
A new AED 8.5 High flow power valve.
New Accell Spark plugs.

The Flat spot off idle is gone.

Going to add a bigger accelerator pump squirt nozzle next.
Want a Big Fat shot.

The Old Beast Olds 425 is running good.
Its a Super Torque Monster.
Moves the 1963 Grand Prix like a C5 - C6 Corvette flying down the road.
