Hello,
I have a replacement engine in my car,engine number B39500470.
I would like to know which model and year this engine came from.
It has twin stromberg carbs fitted.

Hi Mike,

If I'm not mistaken this should be an alpine series 5 engine..
But with other carbs then as the alpine's are tilted upwards because the angle of the engine is different..
This should also have a different camshaft..

Regards Thomas

Hi Mike, It isn't a Rapier one unless it is 305nnnn not 395nnnn then it would be a 1592cc IIIA engine. So, I think Fastback Thos. is right with a 1725 Alpine engine...unless someone knows different . G

The carbs tilt towards the engine and the dipstick enters the block without a tube.
The twin exhaust headers from the exhaust manifold have some painted writting "fast" that someone has put on, so they are fastback pipes presumably.?

The alpine exhaust and inlet manifolds aren't interchangeable without modification..
So i guess the manifolds on the engine in your should be of a fastback...

Alpine chassis numbers were B395nnnnn for the series V.
