Stage 1 : £ 3,619.00 Plus VAT
Stage 2 : £ 3,773.00 Plus VAT
Stage 3 : £ 4,246.00 Plus VAT
Stage 4 : £ 4,834.00 Plus VAT
All dependant on condition of other ancillary parts used in your vehicle, such as : Radiator, fan assembly, starter motor, alternator, power steering etc.
We would prefer you to inspect the tuned engine in an ‘Exploded’ state prior to having it fitted. This is so that you can see that you are getting the specification you are paying for i.e.
Gas Flowing of Cylinder Heads
Size and type of Valves
Pistons, Bore sizes etc.
Also our Stag conversions include the Capri type sump. This is baffled to prevent oil surge.
As you can see by the enclosed specifications for the Stag Conversion the majority of parts used are new. The rest are fully reconditioned. Our 12 month 12,000 miles guarantee covers both parts and labour and is printed on the back of your receipt.
We have an excellent reputation to uphold, if you have any problems whatsoever please contact us at the factory.
On pre November 1975 manual Stags we fit Triumph gearbox modification kit. The cost is £ 145.00 + VAT extra to above, but is very well worth it.
We also advise the fitting of a new visceous clutch in the fan assembly. If this breaks down, then it can write off the radiator.
On all Stags we have the radiator pressure tested and cleaned, this costs a further £ 42.00 + VAT.
New Stag Radiator £ 280.50 + VAT.
Heavy Duty Clutches
Price on application.
We are now offering number plates at cost price £ 21.00 + VAT with your own registration number, then underneath ‘ Specialised Engines Stage 1, 2, 3 or 4’ as applicable.

Quote ‘Tune Talk column ‘Hot Car’ September 1977’
"The only Ford to come my way was a Capri MK2 3 litre from Specialised Engines. The engine in that was basically an imitation of the RS 3.100 spec in the MK1 Capri of that name, and in spite of the greater weight of the MK2 (200 lbs. heavier) it matched or improved all the figures on our original test of the real RS 3.100cc.
PRICE : £3,773.00
As Stage 2 but with SE2 camshaft as standard and larger inlet and exhaust valves from standard, as Group 1 with modified carburettor as list.

This our ultimate Road engine for strength and power. As Stage 3 but includes : Steel main caps, tuftrided, crankshaft, ‘decked’ pistons and cylinder block. SEV 3 camshaft, heavy duty clutch.
PRICE : £4,834.50
Full balance with tuned engines, includes : New clutch pressure plate and lightened refaced flywheel. On Stage 1 and Stage 2 engines.

PRICE : £1,571.00
If fitted in conjunction with our Stage 2 or Stage 3 engines, advisable to have steel mains caps fitted into our engine. Additional cost in our engine is :

Prices on Application
Beware, there are some cheap, poorly made versions on the market. Two noted magazines have done full tests on all makes available. At the time the top two were Mobelec and Luminition. In our opinion there are only slight gains up to 4500 rpm, but after this, mainly due to lack of points bounce, it comes into its own, particularly on tuned units. Against this, any failure means a "normal" garage would not, unlike a normal points set-up, be able to fix it. So we advise you to retain the normal
distributor parts and a screwdriver as a "get you home" device.
A fuel pressure regulator which can be used on standard and tuned engines. Designed to save fuel by regulating the fuel feed pressure to the carburettor float
chamber, thereby not allowing the level of the fuel in the float chamber to become higher than its optimum.
Automatic Gearbox Type Cars
To gain full benefits of the extra BHP of our Stage 2 engine with SEV 2 camshaft or our Stage 3 engine, it is possible to have the automatic gear box uprated at a further charge of : £ 479.50 This includes complete overhaul of the gearbox.
On Stage 1 we stipulate a ‘blue printed’ ‘standard’ camshaft. Stage 2 choice of above camshaft or SE 2 type. SE 2 type ‘Fast Road’ camshaft, but tractable which can be fitted without modified cylinder heads to produce 16BHP increase with modified carburettor (subject to condition of other ancillaries).
SE 3 Camshafts
As SE 2 camshaft but specialists cam made from blank to ensure perfect timing.
This is much more important than on a new car, as some of your ancillaries, such as radiators, heater radiator, gearbox, exhaust system etc, could be as old as the car itself. It takes a new engine approximately 4,000 to 5,000 miles to loosen up, so bear this in mind regarding performance and economy.
The ‘old’ Stag V8 produced :
Maximum Power (net) 145 BHP @ 5,500 rpm
Maximum Torque (net) 170 lb. ft @ 3.500 rpm
The ‘Standard’ V6 Ford :
Maximum Power (din) 138 BHP @ 5,000 rpm
Maximum Torque (din) 174 lb. ft @ 3,000 rpm
With our tuned engines, depending on the condition of your ancillaries and which camshaft and stage of tune used, there are gains up to 194 BHP with plenty of torque.
We stress these are not cheaply ‘rebuilt’ engines, in fact they are hand built tuned units producing more power than the original V8 engine (not less as with the standard mass produced engine).
