95 lt1 block?

Is it legal to run a regular old style Chevy block rather than a LT1 block in a 98 Camaro in stock eliminator ?

Yes, as long as the main bearing size is the same. In other words, you can't run the small main journal Chevy pre-1968 block.

The blocks are NOT a direct replacement. The LT block has a completely different cooling routing system, unique front drive distributor, different timing cover, etc.

Others have converted an LT engine to a earlier generation block, but it's not that easy.

Maybe in Superstock, but in stock you must use the Opti-spark, which requires the LT1 block.

MSD and stock GM Opti-spark's will work the traditional style sbc blocks.

Inquiring minds want to know how to do this ? What would you use as a waterpump ?

Standard sbc water pump with spacers to clear distributor. Water flow can be either direction, these motors don't see enough temperature to need the reverse cooling.
