Finally, after searching forever for the "perfect V for me", I found it and it is now in my garage.. I bought a 2012 Black Diamond sedan. I drove from Illinois to Texas last weekend and picked it up. It has a ZL1 lid, Airraid CAI, trunk mount ice box (which I didnt even know till I got it home.. lol), and electric cutouts with remote. No Recarro seats but I'm OK with that. It does have the panoramic sunroof which will be nice if it ever f'ing warms up here. I need to check on the injectors to see if they are still factory or have been upgraded. The only real downfalls are that someone decided to wipe the dirt off it with a dry rag because there are microscratches galore and it had 87,000 miles but LSA so whatever.. Definitely, looking to get a few more cheap-ish mods before summer with porting and headers in this coming up this winter. So on to my main question.. Can I run a 2.3 pulley with the current mods or should I start with a 2.55?
