Engine number

[Tony Griffiths]

If the car has a "standard" vintage engine, like the one below, it should (unless tuned in some hidden way) have about the same performance as one made from 1924 to 1932 (though during that time the compression ratio was raised a few times). It's very easy to fit the later manifold with a side-draft carb (as shown in picture 3) and even the later cylinder head with its 2-bolt top water-take-off manifold. All are relatively common modifications.
