Solid Roller Lifter Selection

When I got my 470 stroker in 2016 the Comp 829s were in it for 3 tears. Prior to that they were in from 1998 to 2013. Them and the valve springs were changed in 2013. About a hundred runs per year (estimated). Some street miles. 7000 rpm every run. With the nitros Fogger system it reved to 8000 rpm. Probably close to 400 runs with the nos. Kim
