Identifying engine size
Discussion
hi all, i'm normally in the TVR forums but popped in for some advice.
My sister is into mini's and has bought another one on a 'B' plate, supposedly fitted with a 1380 Metro lump. I'ts fitted with a Weber 45 and LCB, with the scuttle crudely hacked about to get the carb in.Since the 'installation' it's not been on the road, and was bought without hearing it run!!! Shell is good though.
This was because a late distributor was fitted and the seller did'nt know how to wire it. I have got it started with an earlier 998 dizzy, but it dies over about 2000 rpm with very rough idle.
I doubt it really is a big bore motor, no evidence of any recent assembly etc, looks like it's stock to me,and is in a bit of a state, but how can I tell it's origin without dismantling it?
Any advice much appreciated.

Thanks for the super quick responses, will give it a try.I intend to remove the weber at some point, I have a 1.5" SU and minispares manifold,would that be OK if it is a 1275? I doubt she would insure it on the weber even if it were jetted OK, she isn't a speed merchant anyway.
Thanks again.

Thanks again.

Thanks all for the advice, rang sis up (the car is 60 miles away from me)and of course the engine number plate is missing, just the rivet holes there.
So, looks like it is down to measuring the stroke as sugested to ensure it is at least 1275, it is supposed to be ex Metro taken out to 1380 but as mentioned before it has no sign of any recent disturbance to head or block, although everything is covered (poorly)in thick gold engine enamel. It was a young guy that had the engine fitted, was bought secondhand by him so no known history. May have been modded years back but I'm not so sure. Would be nice to know where to start with it though regarding timing etc.

Ok, all is now revealed. Compression low on 2 cylinders, so took the head off.Head gasket leaking. Its a bog standard 1275. Stroke about 3 1/4", no machining or flowing carried out. No chest covers.
Thanks for all the advice guys, and guru1071, had a bit of luck, picked up the 2 Haynes you mentioned at a car boot on Saturday for £1.00 each, allready had a copy of the blue Vizard bible from way back and dug it out the loft.So,it's head overhaul time>
Thanks again.
