If i rebuild my motor and bore it 30 over will i need to rebalance the rottating assembly for the new pistons i am gonna go with trw forged pistons. Or would it be better to go with a 383 with cast crank, stock rods, and some forged pistons. Can i use the stock rods with out chaging the bolts and how much HP can it handle with the stock bolts.

 

Help Please.........

 

If you are going to use nitrous, you should have a forged rotating assembly, and yes it will have to be balanced, if you internaly balance it, you have to take the weight off the flywheel, stock LT1's are nuetral balanced on the front, externaly balanced on the rear. You can also buy a shortblock that is nitrous ready! If you change any of the stock internals, you will need to balance it.
