I have an 750 cfm Summit vac secd. on my 60 Merc. race car. Friday I started using ,for the first time my F.A.S.T.   Fuel Air Spark Technology   dual fuel air meter with results that I kind of expected by reading the plugs early since I instaled the "337" engine. One thing I noticed and never give any thought to untill I was replaying my runs. I stall an almost stock C/4 convertor at 2000 RPM when I mash the pedal at launch both banks go off the meter lean, 21, or more lean,just for amillsecond which can be expected all air & no fuel. Think Holley here ,because the parts we are talking about are Holley"
I have no experince tuning a Holley acc. pump or squirter system for Drag Racing The squirters are replaceable as the cam that the acc.arm rides on.So my thinking on this is I don`t have much pump shot remaining , because i am pressing down quite abit to get that stall from a mostly converter. if any one is wondering how drum brakes holds it, the hydraulics are highly modified which is another whole story.No bog off the line ,but maybe more fuel shot may help the 60 foot a little .Any thoughts or suggestions are appreciated.  Thanks   Harry Hutten

The cam has a couple positions.  You can put it into the other position to see if it helps.
A bigger squirter will deliver more fuel sooner.

Here's a good vid about tuning the acc. pump.
