Ben, IME a stock MC long block (head, bottom end, etc) is good for 400hp with 
the right header, turbo, induction system and management system.  Balancing, 
and lightening will help in the responsivness and revability, but I'm not so 
sure how much it will increase your peak output.  IMO, knife edging, balancing, 
lightening, etc is going to get you marginal gains in power.

Not to harp down a past thread, but the best place you can spend money to get 
HP is with the _right_ engine management system.

Head Bolts - Not OK.  Get rid of the stock head bolts, the are not 
appropriate for high output motors -  get some ARP studs from Summit racing for about 
$100, in conjunction with a stock HG it will hold up quite well, BTDT many times.

HTH,
Javad

I am proceeding with rebuilding an MC-2 engine and would like to have it 
capable of handling 400HP regardless of whether I crank that much out or not.  The 
engine is in good condition and as expected hone marks still visible on 
cylinder walls.  Over and above deglasing, rings, bearings and seals and a 
throurough cleaning, what else should I spend any money or time.

One consideration is to balance the crank with flywheel and harmonic 
balancer.  I had understood that the MC-2 was already balanced from the factory.  
Should I still have this done?

Any recommendation on knife-edging crank, rods, etc.  I don't want to spend 
any more than necessary if only marginal gains are expected.

Are stock threaded fastners OK to re-use, or should I replace with new or 
something else.

I understand stock headbolts are OK as long as they are replaced and not 
planning to be taking the head off frequently.

Just looking for advice regarding the bottom end so as not to confuse 
matters.  TIA for replies.

Ben
