hey folks, i haven't even purchased my first z car yet, but i'm looking forwart to nabbing a 72 or 73 240Z within the next month. What I'd like to do is drop in a new nissan 3.5 V6 but i'd first like to know how difficult this would be. I know some people have dropped in 350 V8s, but i like that new Nissan engine. I'm sure within the next year or so i could find one in a recking yard for a fair price. I'd appreciate any help, and i look forward to getting my first Z customized with your help! Estevan
