Forgive the threadjack (the project looks cool, BTW!) but might I inquire why you guys are going for the 260z, versus the 240? I understand the extra displacement, and I'd imagine there's more flexibility with carbs vs. the injection on the 280, but I have nightmares of tuning the carbs on my dad's 260 as a child. . whereas the 240 was a relative breeze. What am I missing?
