Con rod query

Thanks both.
I shall be getting the crank and flywheel balanced so may well ask them to lighten the flywheel at the same time.

As an aside, I was talking to a "posh" classic car dealer last week and I asked him the question "If I offered you my Type 65 with its original engine, would you prefer this on a pallet, entirely unaltered, or in usable form in the car?" He replied he'd like to see it on a pallet.
I think this is symptomatic of what's going wrong with classics - the idea that you keep a precious artefact but don't use it seems very sad to me, although probably financially sensible. 
I am hoping my plan will give me the best of both worlds - a usable original engine that is hopefully unlikely to destroy itself, but retaining the original crank, rods and camshaft gear on the shelf so that my children can give the market what it wants when I'm dead (always assuming we're still allowed to drive cars with petrol engines in years to come).

Dealer would say that wouldn’t he, that way he gets 2 bites at the cherry, sells car as is, later sells engine on it’s own. If I was looking for a sports seven I would want one with a correct engine and would pay a premium for it.Probably pay more for one with new crank.I would not run a sports engine with an original crank, not worth the risk, neither would I buy an original Nippy crank I consider them worthless.How things change, a Nippy crank was a must have in the 70s!
