big bore 390ci alloy vs. 402ci iron block Heres the disicion I have to make, ARE sleeved 390ci using stock crank or SLP ZL402 or other 409 iron block.
The SLP 402 is cheaper but the ARE big bore would be better for hp and no weight increase. And could be turned into a 427 or 455 later.
what does everyone think? Its going in a '04 GTO BTW.
