How to date a Hispano T-Head engine.

Having looked at some photographs, it may indeed be a 40hp truck engine as the Alphonso was a monoblock..

I am not a Hispano expert but I do know T head engines somewhat----I have the oldest surviving 1906 Studebaker 4 cylinder Model G 36HP --It is also powered by a T head engine---It is very similar in size and I would think that its size is 35-40HP range ---Generally 4 cylinder T head engines will be 35-50HP of course depending on size but its size and vintage looks about the same as my 36HP motor.

I think Ignacio is right,recently i was looking one (30-40 truck), and provably i would see it again in 15 days, and i´ve one motor picture, but the other side view, so i think it could be the same and it´s to a 30-40 truck.

It looks like an edwardian Alphonso engine and gearbox to me, the earlier cars were 3 speed and the later ones were 4. The Alphonso was 3.6 litres from memory, the 2 studs sticking out of the crankcase were for the camshaft operated air pump for the fuel system and the oil level in the sump was maintained by a neeedle and float arrangement on the side of the sump which appears to be missing. The water pump was driven off the train of gears at the front of the engine on this side and the magneto was on the other side. My guess is the engine is 1912.

Good morning Joris
I have just seen the picture of the Hispano engine and I believe it comes from a 40 HP truck. We are actually restoring the oldest surviving Hispano wich is a 1906 20HP belonging to the Royal Automobile Club of Spain. The second oldest (1907 20-30HP)is also in our workshop because we are ussing it as a reference for some small missing parts Both engines are different to the one on the picture wich is the same as another one we have and wich is a truck engine. If we can get the numbers stamped on top of the water caps on top of the block we will be able to confirm this.
I will send you pictures of both cars at the workshop and the engine.
