Solid Roller Lifter Selection
My 470 stroker was built in 1998 with Comp 829s. 625 lift comp cam. Just over 700 lbs spring pressure. Made over 1000 passes at 7000 rpm. Then the the nitros fogger system went on. Had to shift at 8000 rpm cause it reved so quick. 200 or so passes on nos. In 2013 it came apart for a check over. Only things changed were the lifters and valve springs. 400 runs since. It was also street driven a few hundred miles a year the first 5 or 6 years. Kim
