Upgrade your 400ci to a
455ci |
Using your supplied, or one of our stock, 400 Blocks, we have
sourced and developed a 400 to 455 conversion. |
Details :
-
Re-bore.
-
New Crank.
-
New Pistons (pre '72 dish, post '72 flat-top).
-
For durability it is recommended that the
optional 4-bolt main and steel con-rods are also fitted.
-
Call for full options ,details and prices.
(see details below on how to further
improve the performance and handling of your vehicle) |
Engine External |
Modify
or replace factory fuel and ignition system and removal of emission
restrictions. Optimise the fuel/air
delivery and ignition timing, to produce
maximum horsepower and torque.
|
Options include :
-
De-emission : Modifying intake and carburettor system.
-
Carburettor : Modify you existing carb’s, needles, jets etc
and re-tune.
-
Distributor : Modify advance curve with new springs and
vacuum pod.
-
Intake : Upgrade filters and factory intake, re-commission
that "shaker" hood !
-
Coil : Replace the factory coil with an advanced “sports
coil” and leads,
(please
call us to discuss your requirements as even a simple carb and ignition "tune-up"
can have a marked improvement on the vehicles power and throttle response)
|
 |
Engine Internal |
A
myriad of options available depending on your driving needs, be it
increased reliability, street or race performance.
|
Options include:
-
Cam
& Lifters : improve the dynamics and range of performance
-
Pistons : We recommend the fitting of forged pistons for
reliability
-
Crank : machine, polish and balance
-
Con-Rods : Machine, polish and balance existing or upgrade
to a forged steel
-
Heads
: increase compression – increase power – simple !
-
Heads
: porting existing heads to provide better flow rates.
-
Valves : increase flow (both ways) with bigger intake and
exhaust valves (stainless steel optional)
-
Block
: Clean and de-burr, 4bolt main option, boring and decking
(Many other options available
to suit all budgets and drivability. Please call to discuss)

Exhaust |

With
few exceptions a higher flowing exhaust will improve power, torque and
the sound of your f-body.
How loud do you want to go ? |
Options include:
-
Aftermarket systems
-
Custom
systems to your specifications.
-
“In
house” custom system using "mandrel" bent* and Flowtech parts - supplied & fitted
-
Headers
-
Tips –
stainless and chrome
-
Catalytic converter removal (retaining m.o.t. emission levels)
*Most people use conventional bending
machines that noticeably "stretch" the pipe into shape. E.g. A 2¼" pipe that
has to be bent 90 degrees might end up being 1½". This noticeably restricts
air flow. Mandrel Bent pipes are produced on a very sophisticated bending
machine costing 10 times that of a conventional bender. If you start with a
2½" pipe, all bends stay at 2½" regardless of the sharpness of a particular
bend. These smooth bends allow your exhaust system to breath much better
creating a cooler running engine and enhancing mid range and top end Torque
and horsepower. All in house custom pipes are mandrel bent.

 |
Suspension |
Replace the "stock" suspension allowing better cornering
and stability.
Stiffen the chassis, allowing the power to be transmitted to
the ground,
not through the vehicle |
Options include :
-
Shocks
& Springs : Increase cornering capabilities by increasing the spring rate
and lowering the centre of gravity.
-
Sway
Bars : Increased cornering capabilities with decreased body roll,
-
Polyurethane Bushings
: Alleviate premature failure and spongy ride of factory rubber bushings.
-
Sub-frame connectors : Stiffens the vehicle chassis and body unit.
Recommended for T-Top equipped vehicles and drag-strip use.
(please
call us to discuss your requirements as even a simple suspension "tune-up"
can have a marked improvement on the vehicles handling capabilities.)

Brakes |
Upgrading your vehicles brake components can mean the
difference
between a close call, or a collision - 'nuff said !
We can improve your
vehicles stopping power with a simple brake hose
and pad upgrade. However, if you need more stopping
capability than that,
we can offer a full disc and calliper upgrade. |
Options include:
-
Discs :
Rear drum conversion to disc
-
Discs
(rotors – slotted, drilled, )
-
Calliper
-
Pads
-
Hoses
-

Drive Train |
From the flywheel to the differential.
We can improve or modify each component to suit your needs, from
Fitting
LSD's and changing gear ratios, to fitting competition clutches and high
stall
torque converters
|
Options include :
-
Differentials : Change the ratio for
acceleration or crusie
-
Torque Converters : Improve your launch
with a High Stall torque converter
-
Clutch : High performance "zoom" clutches.
-
Transmission : Overhaul or swap (Muncie,
Borge Warner, TH350, TH400)
