1959 XK150S DHC engine question
Many years ago I started a restoration of a 1959 XK150S DHC. I totally rebuilt the engine, transmission and overdrive. Even had the crank and cams reground. But the body work was beyond me at the time and my pockets were not deep enough to have that much work done so I lost my head and sold it. But my question is about the engine size. As I remember it was a 4.0. But the data that is published today says it was a 3.8. The engine had the gold head which was a 9.0 compression ratio, three two inch SU carbs and was rated at 250 HP. And I believe that same engine went in the first E type cars except bored out to 4.2. Was my engine a 3.8 or 4.0. Just trying to get the record streight.
I know one of you Jag history experts knows the answer.

The XK150S came in both 3.4 (250 bhp) and 3.8 litre (265 bhp) variants. Whichever your DHC was, you had a really rare bird. 104 3.4S DHCs were built, plus 89 3.8S DHCs. Many more 3.4S OTS (open two seater) were built than the DHC - 888 units. Today, you can find more 3.8 XK150S cars than ever left the factory (wink, wink).
Having fun with the two Jags (his and hers) that I have now.
