fommel c 1.1 engine cinversion!?

Alright?

I've just got myself a mk1 fommel c, shes a bit rusty but an absolute beauty. i brought her for 700 quid but it has a shoddy pant job… now my question is how much could I expect to pay for a re-spray if rubbed down/stripped myself.

oh and it has a 1.3 lump at the minute. what size/type of engine would be a straight forward drop in!?
