And why Isky is the best overall in MY world and all I use plus my roller has the most aggressive street-ish lobes while being easy on parts. 14+ years and changed springs twice and rebuilt the roller lifters once so far. Easy mid 9's and 6-teens so far and driven a good amount.......680-.660 276-281 on a 108 lsa w/97 degrees of overlap.....
