I would go with an l32 block. Higher compression.
Any of you guys have some tips on pulling the block? Can I do it without removing the front cover? I really don't want to have to jack it up where it is and remove the balancer and front cover from the wheel well.
EDIT: Also, IF my block is trash and I need a new one, and not only pistons, should I go with a NA block and do a top swap on it, or should I just try and stick with a L67 or L32 block?
