Hi all,<br clear="none">
<br clear="none">
This year (2013) at the Silver State Classic Challenge, I recorded a
top speed in the trap of 130.7 MPH. When I reached the countdown to
the trap I was already doing just shy of that to bank time before
the Narrows. I consciously pressed the accelerator a bit more to
push her up to a goal 135 MPH, but nothing happened.<br clear="none">
<br clear="none">
I speculate at 130 MPH, I'm using up all the carb, or all the fuel
pump. One, the other, or both.<br clear="none">
<br clear="none">
The Carb is a Ford stamped Holley list with these numbers:<br clear="none">
<pre>D8PE-9510-KA
LIST 8414
3113

obtained.<br clear="none">

Apparently it's a 600 cfm. it has vacuum secondaries and
three-quarter turn emission lockouts on the mixture screws. I've
put a standard rebuilt kit through it once or twice. It's been a
really good carb, but I don't know it will pull more than 130 MPH.<br clear="none">
<br clear="none">
What to do.<br clear="none">
As always, money is a bit of an issue. I'd like to install EFI but
that's really expensive.<br clear="none">
I'd like to keep it responsive at low rpm like she is now, but still
have the throughput needed at higher rpm at top speeds. I think
this leans me toward a vacuum secondary rather than mechanical. I'm
sure the cfm needs to be cranked up, but would 650 do it or should I
head for 700 or higher?<br clear="none">
<br clear="none">
Does anyone have one they'd be willing to part with?<br clear="none">
Should I send mine into someone like Chuck Nuytten and have them do
their magic on it, replacing metering blocks and other mods?<br clear="none">
Should I just buy a new one?<br clear="none">

I've got some time so I'm looking for some informed/experienced
opinions on what carb would be best.<br clear="none">

And since Professor Engles from the Midwest Division of the Pantera
Research Institute is engaged with Fuel pump questions, I'll just
follow his thread on that part. :)<br clear="none">
