soaker Posted April 14, 2008 Report Share Posted April 14, 2008 (edited) You can run solid lifters on a hydraulic cam with no problem. Many people have done it for years. Edited April 14, 2008 by soaker Quote Link to comment Share on other sites More sharing options...

Matt Ohm Posted April 17, 2008 Report Share Posted April 17, 2008 if u ar running the anti pump-up lifters u will have alot of play when the car cools off but when the lifter pumps up at high rpm they will be fine. i had the same problem.

fast18 Posted April 24, 2008 Report Share Posted April 24, 2008 I always set them cold and with the car not running. I have never had any problems when I do it that way. Quote Link to comment Share on other sites More sharing options...
Truck99 Posted April 25, 2008 Report Share Posted April 25, 2008 Personally, I would not put solid lifters on your hydraulic cam. It can be done, but you may as well install a solid cam at the same time if you're going to that trouble. A few ideas to address your problem - when you set the valves, do it with the motor off. When the valve your are setting is completely closed, tighten the nut with one hand while spinning the push rod with the other hand. When you just begin to feel tension on the pushrod, you should be at zero lash. Tighten the nut no more than 1/4 turn beyond that and move to the next rocker. Use anti pump-up lifters for sure. If you're not already, use polylocks. The stock type nuts will back off on their own under race conditions. If you do this and you're problem persists, make sure the studs are not pulling out and/or the cam is not going flat. Quote Link to comment Share on other sites More sharing options...

If for one reason or another it may be a big expensive mess to clean up if it doesnt work. Quote Link to comment Share on other sites More sharing options...
jakdad Posted May 4, 2008 Report Share Posted May 4, 2008 I believe that if you put solids on your cam, you might as well change cams. You will have to very soon anyway. Quote Link to comment Share on other sites More sharing options...
