During the first dyno pulls, the A/F ratio
was way too lean (13.7:1 on E10
87-octane pump gas). We stepped up
the primary jets from 66s to 74s, and
the secondaries were increased from
70s to 78s, which provided a 12.4:1 A/F
ratio at WOT. If you have ever changed
jets in a Holley carburetor, the Brawl-
er’s jets are swapped the same way.
The primary power valve is a 6.5, and
there isn’t a power valve in the second-
ary metering block.
After the jet changes, we readjusted
the float height for each bowl. The
float-height adjustment is the same as
every Holley carburetor. The oversized,
built-in float bowl sight glasses make
the fuel-level adjustment an easy task
to complete.
We installed a Hooker clamp-on O 2
sensor bung (PN 71014302-RHKR) to
our exhaust. In the future, we may weld
in a permanent bung, but the Hooker
clamp-on setup was easy to install
and provided leak-free operation. The
Pennsylvania College of Technology’s
Mustang chassis dyno had an O 2
sensor that we connected to the new
bung to monitor the A/F ratio.
