Please support the sponsoring companies who make www.BritishRaceCar.com possible, including:
BMC B-Series 1.8L four cylinder engine.
Fab-Tek roller rockers provide a higher lift ratio (1.6:1) and more stability at high engine speeds.
The rocker arms themselves are actually Chevrolet Cavalier parts. Their use on an MGB requires
machine work on the cylinder head, plus adjustable pushrods, a mounting plate, and an oil spray
bar mounted to the valve cover and fed by a braided hose from the main oil galley, as shown.
Moroso cooling system expansion tank.
Later model MGB dual-circuit master cylinder.
Holley fuel pressure regulator.
Fab-tek exhaust header. Note also shortie aluminum velocity stacks.
Howe aluminum radiator (part# 342MG1).
Stef's Fabrication Specialties overflow/breather tank.
Howe aluminum radiator's lower tank and drain petcock.
Oil cooler. Note also aluminum front valance.
ATL fuel cell. Holley "red" fuel pump. Fram HPG1 fuel filter.

The suspension crossmember is mounted on polyurethane pads.
Fab-tek tubular front anti-sway bar, on aluminum pillow blocks.
Early-model MGB "banjo" axle, except with later-model "Salisbury" tube axle ends spliced on because
they provide heavier duty bearings. Banjo and Salisbury MGB axles utilize the same brake components.
The banjo axle is preferred because it's lighter, and because more appropriate gear ratios and differentials
are readily available for it. (The aluminum "pumpkin", shown here, is a standard feature of the banjo axle.)
Fab-Tek anti-tramp bars.
Fab-Tek rear anti-sway bar.
Note that knee action shock absorbers are being used, except with adjustable Heim-jointed links.
A quick release steering wheel hub makes it easier to get in and out of the car.
The electronic module (left of the steering column) is part of a Traqmate GPS data acquisition system.
Moto-Lita steering wheel.
ButlerBuilt seat and Willans 6-point cam-lock safety harness.
This car was converted to right-hand-drive. Alan learned to drive on the right, back home in England.
Another reason to prefer right-hand-drive is that all the tracks Alan races on are clockwise. In terms
of weight bias and driver visibility, right hand drive provides a small advantage on right hand corners.
The red lever (in foreground) is for the Wilwood adjustable brake bias valve.
Cooling system overflow tank, fuel supply line (3/8") and the oil hose to the Accusump (1/2").
2 quart capacity Accusump cylinder. Accusump provides oil flow before engine start-up.
Alan awaits the start of the 2009 Collier Cup Feature Race at Watkins Glen International.
Genuine Minilite "MagStyle" Made-in-England wheels from Targett MotorSport.
(These wheels are available in silver, gold, white, anthracite, satin black and gloss black.)
A reliable MGB like Alan's can compete in five different races in one Watkins Glen
Vintage Grand Prix weekend, plus multiple qualifying and practice sessions.
Staging for a race at V.I.R. - Les Gonda stands by.
Sebring headlight cover. Note also the re-located bonnet release knob.
GT Classic mirror.
Emergency shut-off and battery disconnect switch.
Factory hardtop, and "Sebring style" rear valance.
This is a period vent, as fitted to some of the Competitions Department's MGB's.
Shoulder harness attachment bar.
Minilite MagStyle aluminum wheels.
Hoosier "Street T.D." P205/60D14 bias ply tires.
