Duke,
When I installed my F4B I closed off the exhaust pass over that runs under
the carb area. This helps in keeping the carb a little cooler.
The propose of this passway is to help vaporize the air/fuel mix, but as
everyone knows heat isn't something we lack in Tigers.
It MAY take a little longer to come up to temp, but that's hardly a problem
in Tigers.
Some gasket kits include these little block offs, I made two of them from a
piece of SS, just make sure that the piece you make is THINNER than the
intake gasket and fits inside of the hole in the gasket.
Another plus is no burn area on each side of manifold just below the carb.
Perhaps this will help.

so far).

Subject: [Tigers] Intake manifold....carb boil.
I was hoping to find answers to this issue at SUNI. I did not.
I also checked the archives.
I have a chronic problem with fuel boiling in the bowels and flooding my
engine. This happens when I stop the car once it is up to temp. I saw
other Tigers with the same issues at SUNI.
My current equipment -
260 bored 030 over
F4B manifold
Holley four barrel carb (custom)
OEM Hood
Slightly modified fuel delivery. (line runs up the tranny tunnel to back of
carb and has heat shield sock)
The car runs cool and does not go above 200 at idle or on the freeway.
What I am thinking about doing -
Edelbrock Performer (low rise) manifold. The F4B leaves no room for any
spacer.
1/2 wood carb spacer
Recirculation fuel delivery system
LAT 79 hood
13" Electric pusher fan and will run on timer for 5 minutes after engine is
shut down (need to find a timer) and/or when the coolant temp is over 210.
What are your thoughts? I am really looking for info on what the
performance of the Performer manifold is compared to the F4B.
