I am trying to identify the origin of a forward control engine in my Series III. The engine number is 314xxxxxF. I am not even certain this is an FC number. According to Glencoyne.co.uk, 2.25 FC engines start at 325xxxxxx. The current engine is a diesel with a mercruiser valve cover, and it runs clean and strong, so my main reason for looking into the history is to determine whether it is a conversion from a petrol engine or if it is was originally a diesel marine engine. The number on the crankshaft is R2254B. Any info at all would be very much appreciated.

Jason,

As many off the people here will know better as me, i don't think you are in the right forum.
You mention a diesel engine and the Original 101FC never has been build with a diesel engine, only 3,5ltr V8 Petrol.

I think you probably mean a FC 2B or 2B, they might be build with a petrol engine.
but to my knowledge these where build with a 6 cylinder engine.

But for series 2 questions, there is a series 2 club in the UK, they are very helpful and have an active forum.

Or maybe someone here can give you an answer.

Good luck in finding youre answer

Sounds like the 2.25 Diesel a la land Rover, often rebranded Mercruiser 165 and fitted in marine applications.

325 sequence engines were 2.25 petrols for IIB FC's. The diesel model sequence would have been between 325 and 339, whilst there were no diesel IIA FC's, all IIA FC engines (off the top of my head) had 2xx prefix numbers.

The 314 prefix doesn't register as a 'Land Rover' production engine, so the Mercruiser rocker cover is probably a good pointer towards its origins.

The point about being the wrong forum is reasonable, except that I found the following text at http://www.glencoyne.co.uk/engno.htm

300xxxxxx Series IIA petrol 2625cc (Forward Control)
325xxxxxx Series IIB petrol 2286cc (Forward Control)

My 4 cyl 3mb block number falls right in the middle of these two, so the S2 and S3 folks are going to send me right back here. Despite the mercruiser valve cover, it could still be a forward control petrol block with a diesel conversion, right?. Does anyone have a more complete set of engine numbers for the forward controls?

Thanks daslandroverman. That's helpful. I'll move along. If anyone is interested in what I find out, let me know and I'll post it here when I have more to go on. I wish I could get a list of land rover marine engines. I'd be thrilled to find out this was originally built as a marine diesel rather than a custom conversion from petrol. Fewer issues to worry about the crank, bearings, etc.

The point being here that the 101" Forward control, for which this site is about, is a completely different animal to the IIA & IIB and all production models left the factory with the 3.5L V8 and Gearbox as per the Range Rover.

The series 2 club, as recommended do cater for the Series 2a & Series 2B forward controls also, as do the Series 3 & Forward Control people.

This club as explained above is for the completely different oddball military only 101 forward control. hope that makes sense?

another suggestion is to try the http://www.900club.org/ forum, that is a ALL Forward Control and 1 Ton specialist forum,

Thank's everyone for your patience. I think the mystery is solved. After many months of googling and cruising forums, I stumbled across a cross-referencing table in a marine engine stern drive web site. There it is,... mercruiser engine numbers starting with 314 were built by Rover and, as far as I can tell, were diesels. Turner Engineering has confirmed that the cyl head is from an early 2A engine. I will go away now, but thank you for bearing with me. Those "FC" numbers at glencoyne really threw me off.
