Morgan engine???

[BennyHill]

I have noticed that the engine number on my 4.0 Chimaera is 47A05473B and CR 9.35:1. (Rimmer Bros states this as a Morgan engine). The V5 for my car states the engine number as 37A40P4186 (Rimmer Bros states this as a TVR 4.0 with a CR 9.80:1).

So, at some time the engine has been changed....

My question is what is the power difference between the 4.0 Morgan engine and a 4.0 Chimaera engine??

Rimmer Bros have the data on their web site:

I have now found the second engine number stamped on the front of the block, and it matches the number on my V5. So, my engine is the original TVR unit and has not been changed

Thanks for all the help.
