So I have a 2013 v2. The car had 3 pistons fail. I brought it to a shop and they said the block was also toast. The shop is telling me to go with an ls3 block instead of the lsa block (for price and to do away with the oil squirters) I'm planning on putting forged pistons and rods, as well as a cam. My question is the Ls3 block a good switch, or should I save and go back with the lsa block? For the block, pistons, and machine/shop work I'm looking at $8,700.
