the mechanic involved in the restoration (in 2006/2007) said this about the engine:
wat I was told its a 998 block whith 1100 (1098) rods and pistons, crank shaft this is pretty common as the 998 block is easier to find they are basically the same engine the cylinder head is the 1100 head as well as the gear box is a 1100 (syncroniser on 1st gear)
does this sound about right?

Yes, the only real difference between an 998 and a 1098 are the crank and pistons, so it could well be a 998 converted to a 1098. You would have to measure the stroke to be certain.

You can check this by putting #1 piston on TDC. Get a pencil or something, stick it down the hole as vertical as possible and mark the top of the plug thread on it. Repeat for #2 cylinder without moving the crank.
Difference between the 2 marks = stroke.
998 = 76.2mm
1098 = 83.7mm
Difference on a stock motor = about 8HP and 8 ft/lb torque, in favour of the 1098. Well worth having for a road car.
