A rebuild was done over
12 weeks and I spent 35 hours per week on the car aswel as doing a full time
job. The job list included the following.....
Engine....................Rebuild. Regrind crank, recon and port heads,
bigger cam, rebuild and port the carbs, rolling road tune up.
Steering.................Rebuild the rack, replace the bearings in
the column, make double shear brackets for the steering arms.
Brakes...................Overhaul all the calipers, fit twin master
cylinders and balance bar.
Pedals....................Move the pedals further forward to increase
leg room.
Seats......................Strengthen the backs and add head rests.
Suspension............Replace all pivots with new Aurora spherical
bearings, replace front ball joints and lower arms, move rear coil overs further
out.
Fuel........................Remount existing tank, replace SU fuel
pumps with a Facet pump, make special place for spare can.
Exhaust..................Build a new system with proper silencer and
smaller bore pipe.
Chassis..................Strengthen by adding crossmembers,rebuild
from rear axle back, repaint where necessary.
Battery..................Replace the twins with a single unit.
The engine rebuild is
a low cost one but this does not mean that I can not spend time checking all
the parts I would reuse. The pushrods were checked for straightness.
------------------------------------------------------------
The push rods were held
in a jig and pushed straight.
-------------------------------------------------------------
I spent along time just
cleaning components of the engine. The cylinder heads were blasted, the valve
guides were replaced with bronze items. These were machined to take Crane
Teflon seal. The valve seats were cut to 3 angle and the valves refaced. The
heads were ported. The crank was reground and new bearings fitted. The block
was aligned honed to true up the main bearing housings. A Crane cam was fitted
(approx 280 degree duration ), with Crane bleed down lifters and double valve
springs. A long time was spent getting the lifter preload and installed spring
height correct. ARP supplied the fasteners to hold the bottom end together.
New timing gears and oil pump gears were fitted. The SU carbs were rebuilt
and ported internally as per David Vizard spec.
---------------------------------------------------------------------------------------------------------------------------------------------
The rebuilt engine back
in position. The block has been repainted. All hoses are replaced.
-------------------------------------------------------------
The rear coilovers are
moved as far out as possible and the bar under the axle is removed.
------------------------------------------------------------
The chassis from the
axle rearwards has been cut out and will be replaced.
------------------------------------------------------------
The new chassis with
mounts for the petrol tank and cover, so the tank will be isolated from the
passenger compartment.
-------------------------------------------------------------
As I was only going to
have one battery the spare fuel tin can sit in the space left. The fuel tank
is nearly in the same position but the mountings are better.
-----------------------------------------------------------
The silencer is a big
American item fitted up in the chassis. The fuel pump is a Facet red top race
pump.
------------------------------------------------------------
As I was only having
a single silencer I made a 2 into 1.
-------------------------------------------------------------
The new battery and silencer.
There is good insulation around the silencer.
