Re: Drag racing
this is probably a dumb question but exactly what do you mean by surge? just making sure I'm following you. Also if it is a holley650, on the front of the air horn will be a 4 digit number. it will be something like 4150, 4160, something like that. Do you have the site windows on the side of the bowls? mis-adjusted float level can cause various issues.
Others are also on the right track with the fuel line size, etc... Do you know if the acc pump has been changed out for a bigger diaphram?
