Edelbrock Performer Modifications
by George Nenadovich
This is the divorced choke set-up for the Performer intake.
This is a Chevy unit removed from a 72 Impala. Both 2 and 4 bbl Chevy engines
use this choke. This one was from a 2bbl and the choke rod to the carb was
shortened and rebent. Also, notice the slot cut into the side of the choke
cover. Without it, the rod was contacting the cover and the friction prevented
the rod from closing the air blades.
Here is the choke rod placed in the STD hole. The hole to
the left is stamped ALT. Engine is cold and the rod is up closing the air
blades.
This is the factory 1970-2 cruise control set-up. The vacuum
motor with the ball chain has a brkt which screws to the throttle cable
holder. This keeps the pull chain in a straight line.
In order to keep the pull chain in a straight line, I had
to fabricate this small bracket(white arrow) from some square aluminum bar
stock. The vacuum motor need to be raised about 1.5". If you bolt this
vacuum motor in the stock location (directly to the back of the head) You
will not be able to line up the vacuum motor bracket to the throttle cable
holder.
In order to install a PCV valve, use HELP 42049 and any 3/4"
PCV such as PCV1124 both are available from Autozone.
