This is the setup i was looking at doing after a seller backed out after i won a block on ebay last night...i have a 99 si i was going to take my stock block (b16a) get it bored and honed for the 83mm pistons and put the rods (for LS) and a LS crank in it but ive been looking at cranks and it seems like they make alot of different size cranks for the LS b18a/b motors what crank and/or different parts would i need for this setup to work??????????if anyone has any good knowledge about this please share i need to know by tonight maybe the latest tommorrow or if anyone could call me with some insight it would be much appreciated thanks so much

ls crank in b16 doesnt work, block is 5mm to shorter. put it together and the pistons will go right out the top of the block,just get an ls block and put pistons and rod bolts in it, way more power
