Thank you for the welcome. Eric, why a short deck. How many rebores left if you start at 540. What stroke and rod length. The heads are 110 cc and flow about 670 hp. I had a roller in my ls7 but the lifters jammed. I was told dont run rollers on the street, they dont like to idle. What is the prob with a bronze dist gear. Will a 671 get me to the 700's. I just noticed you have what I want. Tell me about your Chev.
