3.5 & 3.6 Conversion

When we first produced the 3.0 – 3.1+ conversions in 1988, our main concern was for reliability and smoothness, closely followed by improvements in both torque and BHP, aligned with reasonable fuel consumption and price. All this equal a good fast road car -not and unreliable ‘cammy’ and ‘juicy’ semi-race type.

We believe we achieved all our aims.

In developing the 3.5 – 3.6 range, we hoped for similar gains. Initially we tested three ‘stroker’ crankshafts of 84, 85 and 86mm, with various bore sizes.

All gave considerable gains in torque, but small, rather disappointing gains in BHP compared to 3.0+ and 3.1+ engines, due to the restrictions imposed by the standard electronic fuel injection system (EFI) used by Ford. Although with carburettored or earlier Bosch type injection systems, BHP is improved.

We can supply a remapped addition to the EFI system at an extra cost of £200.00 + VAT (Fitted).

We have found that a stroker crankshaft of 84.32mm, with a choice of bore sizes as above giving 3.5 to 3.6 litre is the most reliable and fuel efficient of these conversions.



All these engines will fit in place of ALL 2.8 engined vehicles, such as Capri, Cortina 2.3, Granada, Sierra, Scimitar, TVR, Panther, Kit Car derivatives.

08 Price to Stage 1 specification

09 Price to Stage 2 specification

10 Price to Stage 3 specification

11 Deposit Required on all 3.0+ and 3.1+ engines as these are only built to order.


11a We can also do Low Compression versions of all the above, for use on Turbo, Supercharged conversions.

12 Big Engines for Small

13 Your 2.3 V6 for any of our variants of the 2.8 as per specifications. Simply add the surcharge onto whichever variant you have chosen. You will also require Carburettor, Distributor and Inlet Manifold. Prices for these on application.

Additional Parts for Extra Power and/or Strength

Our modified engines are built for normal ‘Fast Road’ use, with the emphasis on retaining or increasing Torque coupled with an increase on BHP, smoothness and gains in petrol consumption, relative to extra power gained.

14 Performance Camshafts

Bearing in mind that any good performance camshaft increases BHP but invariably means a loss in torque. The general yardstick is the “higher the lift, the lower the torque”. Our ‘Fast Road’ camshaft develops up to 12 BHP more, depending on application, with only a slight loss in torque.

15 ‘Fast Road’ Camshaft with our Engine

16 ‘Fast Road’ Camshaft without our Engine

17 ‘Fast Road’ Camshaft outright (made from blank)

18 Modified Timing Gears

Fitted with our modified dowels to give accurate valve timing, fully set up and timed on your engine.

On some modified engines, cam and/or modified gears are already included in the price. See specifications.

19 Tuftriding

This is a treatment used in competition cars for strengthening metal.

20 Crankshaft Tuftrided

21 Con Rods Tuftrided (set of six)

22 Gas-Flowed Cylinder Heads

This process involves machining the rough cast from each of the inlet and exhaust ports, also the combustion chambers (where applicable) to achieve better flow to each cylinder.

23 Stage 1 : As specifications

24 Stage 2 : As specifications

We can also do lower compression versions of the above heads, for use on Turbo, Supercharged or Low Compression Engines.

25 Engine Balancing

We all know the results of a road wheel that is out of balance. The same applies with individual engine components which, when out of balance, result in stress, vibration and increased wear. By removing metal at certain points, major moving parts can be balanced to fine tolerances. The result is a noticeable increase in power from a smoother engine that runs sweetly with increased economy.


All our modified engines have a ‘half balance’, i.e.. the balancing of pistons and con rods. (See specifications). The ‘full balance’ also includes crankshaft, front pulley assembly, flywheel and new clutch pressure plate (Torque driven plate on Automatics).

26 “Half Balance” Pistons and Con Rods on Standard engines only

27 “Full Balance” All engines

28 Heavy Duty Clutches

29 Heavy Duty Clutch Driven Plate

30 Heavy Duty Clutch Pressure Plate


Removing metal from piston crown and/or block to equalise piston heights to achieve absolute balanced compressions. Included in some stages of tune (See specifications).

32 Carburettored Engines Only

It is advisable to fit a modified Weber carburettor and inlet manifold, if you have a standard carburettor fitted, to allow the engine to ‘breathe’ and so make use of the extra power offered. Specially jetted and choked to fit whichever engine size of state of tune required.

56 (A to G) Same Day Fitting Service

We set our fitting charges at a very reasonable rate. This is to encourage our customers to take advantage of this very important service. We have very few problems with our engines, except when they are fitted or set-up incorrectly by DIY or outside agencies, which can mean more expense and in convenience for you, as the fitting is then not covered by our GUARANTEE. Whereas if we fit it, the fitting and all parts supplied are completely covered by our guarantee. Upon your arrival at 7.30am the engine is allowed to cool, then removal of the old engine proceeds. You are then shown over your new engine, i.e. the block assembly, showing the pistons, bore and crank sizes etc, then the cylinder head, showing valve type, sizes, springs, guides, seats and gas flowing of chambers and ports as applicable. Every Engine is completely Hand Built and is the Sole Responsibility of One Engine Builder. By 9.30am your ‘old’ engine has been removed. We then ask you to inspect and decide for yourself if you require replacement of any parts, such as clutch, engine mounts, thermostat, hoses etc. If you are uncertain of what you are looking at, we will show you a new part to compare condition.

57 Radiator Testing

The radiator is sent away (unless new) and is tested under pressure to clear sediment, check rate of flow, repair minor leaks and finally resprayed.

Your new engine is then fitted including all necessary gaskets etc. fully tuned and road tested.

Advice on Braking & Suspension

As with all our conversions, please ensure braking and suspension are modified to suit extra power.


Do not expect any new engine to perform to the best of its capabilities until it has done at least 4,000 miles. Also the oil and petrol consumption will be greater until the engine has “loosened up”.

Our engines do not include ancillaries, such as clutch disc, clutch plate, bearing, engine mounts, hoses, clips, plugs, points etc. These are decided by you the customer at the time the engine is removed. (It may be that the car has already had some new parts fitted.) So please allow extra for anything required.

58 DIY Fitting

‘Don’t bite off more than you can chew’ as the Bishop said to the Actress !

‘Have you got the right tool for the job ?’ as the Actress said to the Bishop

Keep everything clean. Use plenty of oil – as Specialised Engines say.

Leave plugs out when first turning the engine over – this will help your ‘old battery and starter motor’ against the new, tight engine. Fill the oil filter with oil, prime it. Set tappets before adjusting time (using a timing light). Read further instructions on the front and back of the engine receipt. PROBLEMS ? STOP ! RING US ! We are here to help you. It is part of the guarantee that you bring the car back to us, for its first service.

Finally – don’t fit it yourself. “We can make a much better job of it and at a reasonable price !” As the Actress said to the Bishop.

59 Unleaded Petrol

Although we offer converted heads, we consider this a last resort. It involves fitting valve seat inserts which can crack, or worse, drop into the bore, causing severe damage. This usually happens through overheating or if the engine is stressed. It is advisable to retard the ignition by some 3 to 4 degrees, which in turn means losing some engine power. In the circumstances we are advising our customers to wait for L.R.P. (Lead Replacement Petrol)to come onto the market. SHELL have stated that they will be replacing their leaded pumps with this, come changeover. They have already done so in most European countries which have banned leaded petrol. They claim that long term tests have shown that it is a safe and suitable replacement.

60 BHP and Torque Figures

Beware excessive claims ! In the July ‘90 issue of Car and Car Conversions’ there was an article headed “CVH Shootout”. One demonstration engine produced just 112 BHP, yet it was – and still is – claiming 150 BHP. Another claiming 140 BHP registered 122 BHP !

61 Rolling Road

The same issue of ‘Car and Car Conversions’ made some excellent points on their uses. This bears out what everyone in the tuning business has been saying for years. Basically, ignore the reading, as there are so many variables to consider. Rolling Roads are fine for ‘setting up’ an engine and its ancillaries, provided that the operator is good and that the comparisons are all done on the same ‘road’ and on the same day. Ensure a new engine has done at least 4,000 miles before putting it on a rolling road.
