Crank balancing

[South Africa]

Are LS1's (1998 Camaro) externally balanced? Put another are the crank and pully/harmonic balancer balanced as one unit or are cranks and pulley/harmonic balancers interchangeable?

Are the OEM pulley and harmonic balancer one unit or are they two units bolted together and is so can they be seperated/

Thanks

internally balanced.

interchange able pulleys from same type of car. f-bodies are different than corvette balancers.

the balancer and pulley are one unit.

Thanks for the input. Perhaps you can also give some advisce on the folowing question:

I recently acquired a relatively new LS1 motor from Turn Key Engine supplies as well as an LS1 from a 1998 Camaro. The accessories on the Turnkey motor are similar to the Truck engine. My plan is to use the accessories (alternator, power steering pump, aircon waterpump etc) from the Turnkey engine on the Camaro block and visa versa. The problem is the pulley system on the Turnkey motor has a different offset from the motor (approximately 20mm further out) to the camaro motor. Ie. the crank pulleys have different offsets. the question is, can I simply remove both crank pulleys and swap them around with all the accessories or are the pulleys matched/balanced to a particular crank.

Any assistance will be appreciated.
