wow, reading only the first few pages and cracking up I have to add that I have a 91 Zr1 and my brother has a 2004 Z06 so i have experienced both DOHC and OHV engines/layouts. The z06 has more down low torque, more of a throw you back in your seat at low or any rpms where our LT5s have to rev up to get that adrenaline feel. His engine is hundreds of lbs less and way cheaper to build, maintain etc. Given our cars were KING until the C5 z06 came out. the z06 is faster and handles better but the LT5 has more potential. I have ported plenum/IH catback and a tune and I was neck and neck with the stock c5 z06 but he eats me up in the twisties. At the end of the day I love my car more bc of its rarity, group of people, car guys that actually know what a zr1 is, no blind spots, and I **** on my bro every chance i get by saying i can take my top off.....plus his girlfriend likes my car more lol. Long live the KING
