The LS is a much better design as well.
I never liked the flawed idea of optispark being located under the water pump on the lt1. Its a disaster waiting to happen even if you get the lt1 swapped in. I vote LS style

GENIII all the way. the LT1 was good in its time but IMO is way out dated. and like show&go said the distributor is an ax-cident waiting to happen. 1 time with this happening and youll regret going with a GENII.

LS1 is overrated.
I would go with the LT1. More power for your buck.
