the mini has a working 998 in it at the moment but i purchased a 1293 from an accident damaged car so it would have a bit more go

i have spent about £360- £400 on the engine and i know its a good runner.
it has:
roller rockers (decent ones)
some head work has been done as the ports are larger than standard and seem a lot smoother
also the shape of the combustion chamber is different
vernier duplex timing chain
a 2" su with pipercross filter + a intake manifold modified by me
a decent cam(cant remember what it is though)

the bores are immaculate (still has visible hone marks) and the piston tops look almost new
the clutch is an uprated one and it has a hardened diff pin
i have a full gasket set
all new service items like plugs, fuel + oil filter and stuff
will also be selling with it a ford edis module and crank trigger/ sensor kit so it can have electric ignition
i have stripped all the manky old paint off and treated it to a new coat
at the moment the head and clutch cover are off and there are no ancilliaries
so what i need to know is what is a good asking price?
i have a possible buyer offering £350 but i think its worth more
