Background

The Americans sell a lot of cars. At one point Ford was selling an F150 pickup truck every 19 seconds. Yes, you read that correctly. And of course, the pickup truck is as American as pumpkin pie and cherry cola – just as the MGB is as British as cricket on the village green and a pint of warm ale. So how did the little British sports car become the USA’s favourite in the 1960s?

American petrolheads’ love affair with what they actually refer to as LBCs (Little British Cars) goes way back before the 1962 launch of MG’s latest sports car. Way back, in fact, to the MG TC which was introduced at the end of World War 2 in Europe, in 1945. ‘Export or die’ was the UK government’s slogan and MG took it fully on board, shipping the majority of their Oxfordshire plant’s output across the Atlantic.

The American’s loved it – so much so that it actually started what became known as the ‘sport car craze.’ And thankfully for MG, their octagon badge was now hanging in garages all across the land.

The T Series MGs were finally replaced by the MGB’s predecessor, the MGA, which retained a separate chassis but featured more modern, aerodynamic bodywork and, in its final form, a 1622cc version of parent company BMC’s B-Series OHV engine.

MG was already working on a replacement to the highly successful MGA in the late 1950s and prototype development was completed early in the next decade, leading to the new model’s launch in 1962.

The MGB looks like a more modern version of the MGA and that’s exactly what it is. The handsome looks are built around a monocoque bodyshell, with the MGA’s separate chassis construction binned in favour of this stronger, lighter design.

However, the rest of the car was remarkably similar – after all, it’d sold like hot cakes so why change a winning formular? The BMC B-Series engine had now grown to 1798cc but retained the twin SU carburettors of the earlier car, and now made a healthy 95bhp.

A four-speed manual gearbox with synchromesh on the top three gears was again carried over from the earlier car, as was the option of an overdrive unit operating on third and fourth, and its output fed a live axle supported on cart springs. That non-synchro first gear was replaced by an all-synchro box in 1967 but the original unit left its mark. MG was worried some drivers would struggle to select first, so they made second a very short ratio to allow people to pull away in it – so short you couldn’t hit 60mph in it, a fact that hampered the car’s 0-60mph time.

Front disc brakes were standard from the off and other than luxurious wind-up windows and a crackle black dashboard rather than the MGA’s body coloured part, an MGA owner would feel at home behind the wheel of the new model.

In 1965 MG introduced the Pininfarina styled MGB GT coupé with a jaunty hatchback and, after London based tuner Ken Costello fitted Rover V8s into used MGBs, BL finally launched their own MGB GT V8 in 1973, just in time for the fuel crisis prompted by the Yom Kippur War.

MGB production finally ended in 1980 after more than half a million cars had been made, and for many it represents the British classic sports car better than any other.

Overview

Classic motorsport is about as much fun as you can have with a fireproof suit on, and what better car to join in the fun with than The World’s Favourite Sports Car, as MG once marketed the B. And this one’s a beauty.

Born in 1970, it was adapted to a racer in 1996, from a restored and fully re-psrayed shell, all new suspension parts/bushes, overhauled gearbox and overdrive unit, and a rebuilt and racing modified engine by Batemans that increased power by 38 BHP. Documentation shown in the gallery states that in 1996, as part of the Historic Road Sport Championship, it had a stellar first season, where it finshed first and second in its first two races, set three lap records in the rounds thereafter, with it ultimately finishing 2nd overall in the championship. By 1998 it was in the hands of a new owner who hillclimbed the car until 2006 upon it being bought by our current vendor. In his 15 years of ownership he has continued to drive it to all meetings and spend whatever was needed to keep it competitive. Today it is running on Webber 45 DCOE with a full Maniflow large bore stage 3 competition exhaust and manifold, Kent 719 race cam, larger valves, lightened and balanced flywheel that together is producing 142bhp. It has a Quaife limited slip differential, overdrive on all forward gears, Gaz adjustable shocks, anti tramp bars, poly bushes, ventilated front discs, green stuff pads, an aluminum bonnet, Sebring front valance, Minilite style wheels with Yokohama A048 E's fitted, which all together has created a powerful, sublimely handling, and ultra good looking example. 

Furthermore, the seller had the engine rebuilt in the winter period of 2019/20 that entailed a re-bore, new pistons and rings, a full balancing, checking head, polished crank, new core plugs etc etc, carried out by MJA Automotive Engineering, It was refitted by Mech Repairs who at the same time fitted the aforementioned uprated clutch, aluminium catch tank, the 719 Kent Cam and new front/rear adjustable shock absorbers.         

Weighing in at 960kgs and producing 142bhp, it retains road legal status, so you could drive it to the circuit, get sprayed with Champagne then drive home again afterwards, although the full race Kent 719 race cam might make negotiating the ring road during rush hour a little taxing.

This car can do it all but it’s built to win races. MGBs aren’t luxurious chariots in standard trim – that’s not what they’re about – but this is a race car, with every part modified or replaced with the sole intention of making it loop a twisty circuit as fast and reliably as possible.

It’s still very much an MGB, but the volume has been turned up to 11 and the focus adjusted until it’s pin sharp.

Exterior

It may be a race car but the fit and finish of this MGB is far better than it would have been when it left MG’s Abingdon factory back in 1972. The white paint gleams and wouldn’t look out of place at a show, let alone on a grid.

The fitted hard top is also finished in body colour, which we think looks far prettier than the black items often fitted – it looks like an integral part of the car rather than an afterthought.

As a racer there’s very little chrome to speak of as bumpers and over riders have no place on a circuit. There’s a little crazing on the trim around the rear lights but it’s a very minor issue and we’re only mentioning it for the sake of completeness. At the front the car sports an early spec chrome slatted grille and Sebring style valance.

The original steel Rostyle wheels are gone and in their place are Minilite style alloys shod with sticky Yokohama A048 E marked tyres (road legal).

Under the bonnet this is still very recognisably an MGB but the standard spec twin SU carbs are replaced by a snorting Weber 45 DCOE twin-choke sidedraught. Matching this highly efficient intake system is a snaking Maniflow tubular exhaust manifold.

You won’t see the big valves in the gas flowed high compression cylinder head but rest assured they’re there, along with a Kent 219 camshaft. Together, this is enough to take the MGB’s power output to 140bhp which, together with the weight loss, make this a potent race car in its class.

Interior

If you’re looking for creature comforts in here you’ll be disappointed but if period race car charm is your schtick, then climb in – watch your head on that MSA approved roll cage – buckle up the Luke race harness and settle firmly into those Cobra race seats.

The beautiful wood-rimmed steering wheel provides plenty of feedback to the budding James Hunt and don’t forget to remove the safety lockout if you need reverse gear while in the paddock. (If you need it on the track you need more lessons at race school.) And watch that switch on the gearknob – it activates the overdrive unit, which in this car has been modified to allow its use in all four forward gears, meaning you can keep that race engine on the boil as you now have eight forward ratios to choose from.

Keep the engine revving because below 3000rpm it doesn’t really want to know. But get it above around 4500 and all hell breaks loose, so hold tight and keep you nerve.

Mechanical

Standard MGB cart springs were marginal with a standard engine so this car has anti-tramp bars to keep car and axle working in sync, and there’s a Quaife limited slip differential (LSD) in the rear axle so all of the 142 horses are transmitted straight to the tarmac.

All the suspension has polyurethane bushes in place of a road car’s rubber versions for better location and durability, and in place of the standard lever arm dampers there are Gaz telescopic units.

MGB brakes are very good as standard – especially in a car denuded of its bumpers and with an alloy bonnet, but this car also has ventilated front discs to help dissipate the heat generated during race conditions.

History

Much has already been stated as to the history and specification, but its worth pointing out again that in 2019/20, before the Covid pandemic scuppered their plans for racing that season, this is a fresh powerplant that has only enjoyed four meetings.

The car is road legal and comes with 12 months’ MoT. All invoices since the rebuild to competition spec' are on file and in the documents gallery which we invite you to have a good read through. 

Summary

Pass me that race helmet, my man. If we were planning on going classic racing (and after seeing this car it’s a serious temptation) then this is exactly the type of car we’d go for. Built well, has great competitive history and a great deal of recent spend - especially on the engine. 

Not only that, as it’s still road legal we could also take it to the pub at weekends, buy ourselves a pint of warm ale, lean on the wing and await the admiring glances.

Our estimate for this car is £15,000 - £22,000.
