Subject: Re: Fw: Stroker getting better,
but still struggling
Vacuum was around 9 if I remember right. Keep in mind I
didn't get the idle down much below 1,200.
The Edlebrock's don't have power valves. They use metering rods,
instead. It's the old AFB design...
Thank you,

what is your vacuum and what size of power valve?
The fuel pressure has to be no more than 6psi. I broke in
leroar at probably 3k rpm and when I let it finally idle it started spurting
fuel and died. With some rpm's it can handle the fuel but not at idle. 7.7
is definitely too much. I put on a pressure regulator and all is well. I
used the Holley unit and do not run return line.

Thanks, Jason. I will try that tomorrow - after getting
some new plugs. Arghh.
It is occurring right around 1,200 RPM. Idles nice around 1,500
- 1,600 but I'm sure I can dial this beast in below that...
If you come up here I promise you will leave with a trunk full of

YOU MIGHT TRY SLIPPING THE HATS HALF

WATCH WHAT THEY ARE DOING

AT WHAT RPM DOES THIS THING GET
NOTICBLY RICH? I MEAN CAN YOU TELL IF AT 1200 RPM IT REALLY
STARTS GOING RICH. OR DOES IT JUST CHOKE UP AS YOU BRING IT DOWN
FROM SAY 1500? IF YOU CAN WATCH IN THE CARBS SEE IF YO NOTICE GAS
DRIPPING INTO THE INTAKE AS ITS IDLEING. IF THE FLOATS ARE RUNNING
OVER YOU CAN SEE IT SOME TIMES.
PS.
HAHAHAHAH SOUNDS LIKE A FUN
PROJECT. MAYBE I SHOULD COME UP FOR A VISIT ON A SATURDAY SOME
DAY
Hey there gang,
Don't know if you recall but I fired up my stroker build late last
year and had a ton of issues. Worked on it over the winter here
and there and many of the kinks are gone. The timing is spot on,
the compression is awesome, I resealed the intake, etc. The beast
runs like a champ now - until it warms up and I try to bring the idle
down for some carb adjustments. When I do so, it loads up,
rich, to a point where it fouls the plugs and stalls out.
As a reminder, I am running two Edelbrock 1405s on the CH-28, with
the Lunati 63799 cam. It's a 440 block that I stroked to
511. I am using 452 heads that I cc'd, so I am just north of 12:1
compression.
Here's some current theories I am chasing:
- I am running an electric fuel pump with a return regulator.
With two different regulators I can't get the fuel pressure dialed below
7-ish PSI. I am thinking I need a bigger return line to get it to
dial back at the regulator./ The reason I am chasing this is I am
hearing from multiple people that Edie's like very little pressure -
like 5.5 PSI - so it's possible the fuel pressure is pushing past the
needle and seat and thwoing off my float settings.
- Tomorrow I am going to change the step-up springs to a weaker
set. Another theory is that camshaft is producing such low vacuum
that I am not keeping the metering rods down at idle
So does any of this makes sense? Any other thoughts or
ideas?
