racerx260 Posted April 4, 2006 Share Posted April 4, 2006 IF I PUT A N/A CAM IN A P90A HEAD W/ HYDRALIC LIFTERS WILL I HAVE ANY ISSUES? I HAVE HEARD THAT THE RAMP ANGLE OF THE HYDRALIC CAM IS DEFFERENT THAN THE SOLID LIFTER CAM. ARE THERE ANY DIFFERANCES IN THE ROCKER ARMS?

Thumper Posted April 4, 2006 Share Posted April 4, 2006 Unless your hydraulic lifters are in tip top shape or have been modified you cannont run an aftermarket cam. Even if they don't make noise doesn't mean they are in tip top condition. Tom I am switching out my hydraulic head for a solid head so that I can run my VERY MILD cam. It would not run on my hydraulic head due to not enough lifter strength at idle. This was with a turbo automatic oil pump with competition springs. 15psi at idle and 55psi by 3500rpms. So oil pressure was not the problem. I also have dissembled and cleaned my lifters multiple times. Quote Link to comment Share on other sites More sharing options...
