the standard single distributor holddown
is difficult to access. So PP have provided dual distributor holddowns
on all Power+Plus Chevy intake manifolds, which gives you an optional
position. And on our 52030
Racing Manifold, you can use two holddowns for extra protection
against distributor rotation.
you want to run nitrous with the injectors mounted directly in the
ports, Power+Plus Manifolds provide a simple solution. Many of the
manifolds include cast-in nitrous bosses which provide the extra
thickness not found in most competitive manifolds without spending
a lot more money. This extra thickness is necessary to provide the
proper amount of thread engagement All you have to do is drill and
tap the bosses to accept any manufacturer's nitrous injectors.
Water Divider Baffle
Power+Plus #52030152031 Manifold is designed for both racing and
has all the necessary bosses and tapped holes to accommodate street
accessories yet it also includes every feature found in manifolds
costing hundreds more. One trick feature is the Water Divider Baffle.
Expensive race manifolds have this baffle cast in place in the manifold
but this precludes the use of a thermostat if you want to use one.
The Power+Plus Manifold is machined for a thermostat but the package
also includes a drop-in Water Divider Baffle for those who desire
Carburetor Adapter Plate
Many Chevy manifolds
accept the stock Rochester Quadra-Jet spread-bore carb. But if you
want to use one of the popular Holley or Edelbrock square bore carbs,
you have to spend more bucks for a carb adapter plate. Power+Plus
manifolds with spread- bore patterns include steel adapter plates
and gaskets to accept square bore carbs. Included with manifold.
Corner Water Ports
of our performance manifolds feature two extra water ports at the
rear of the manifold, a
feature normally only found in manifolds costing hundreds more.
Some enthusiasts have found that plumbing a line between these two
rear ports can reduce engine over- heating. Many racers also find
these ports to be an advantageous special feature for plumbing special
additional water lines.
Special Manifold Adapters
Power+Plus Street and High Performance Street Manifolds
for small block Chevys
come with special adapters that allow these
manifolds to fit the '87-'95 cast iron heads. If you have '86 or
earlier heads, or '87-'95 aluminum heads, PP manifolds bolt right
on without the adapters. For '87-'95 cast iron heads, drop the adapters
in the four slotted holes and bolt up the manifold with no fuss
and no special tools required.
