Conversion from 2.4

[Andrew OD Booth]

Is there a definitive guide on what to look for when buying a Mk2 that has had a replacement 3.4 or 3.8 engine, when it had left the factory with a 2.4?

I'm aware that 3.8s had an LSD, and a 140mph speedo, and I believe the front road springs were uprated for the heavier engine. But how can you tell if all of this has been undertaken correctly?

Many thanks.

On any 60 year old car it is difficult, if not impossible, to tell easily if it has been well maintained throughout its life. When buying one, you just have to be meticulous and check everything possible. Buying an upgraded version with a larger engine is no different. Originally, LSDs carried tags with the ratio plus an extra tag with a marking (an X, from memory) signifying an LSD. However, the tags are easily lost when cover gaskets are changed. Jacking a car and seeing if both rear wheels turn in the same direction is the best way of checking for an LSD. Engine block markings should be examined to establish which are fitted to confirm engine sizes. Upgraded cars deserve upgraded brakes, so to find original brakes with an upgraded engine should act as a reminder to double check the quality of the workmanship involved. Ride height can be a clue to the front springs fitted, but in any case, on cars of this age, it is highly likely that the springs are not the originals. Sight of invoices for parts used during a conversion can be helpful but are not necessarily definitive in the motor trade which is not always noted for its honesty! 'Caveat emptor' springs to mind as the best advice when buying any car, upgraded or not. Mike.
