Solid roller cam???

flamed 98 gt · February 17th, 2009, 08:49 AM

I did use the search button but could not seem to find answers. What is the differece between a solid roller and a hydrolic roller cams. I have a 1990 5.0 lx that saw maybe 200 miles last year. This car is more strip then street and I have thought about doing the swap. What all is needed and is there any advantage to the swap?

the advantages to going with a soild over a hyd. is the much higher RPMs you can rev without valve float, with a solid. In general most solid roller motors are pretty high hp

Valve float is from the springs. you might be meaning lifter float, but that cant damage your pistons. Solid lifters are... solid, and do not have give. Solid lifters require far more attention to valve train setup, and adjustment.

thats the exact cam I want, id trade you straight up if you are interested in the cam I told you about

93mustank · February 18th, 2009, 02:56 PM

Why buy or install a cam based on sound?????? Seems hog wash to me...

86er · February 18th, 2009, 04:10 PM

If you are talking to me, its not based on sound, its got the decent split in duration I want for the nitrous and its got enough lift when added with my 1.7's to keep the lift values where my heads flow max cfm...........

If valve float can damage pistons so can lifter float,it's the same action just at the other end of the valve train, it is the lifter losing contact with the push rod due to high valve train speed valve float is the valve losing contact with the rocker arm.Either way the movement is out of time with the piston

Umm no if the spring fails and the valve floats, the pistion hits it, if the lifter floats the valve still closes, there is just a gap between the rocker and cam.

I dont get it... Lifter float is when a hydraulic lifter stays collapsed. This will not keep the valve open.

Valve float is when the spring does not have time or tension enuf to close the valve. This will keep the valve open.

That article states that valve float and lifter float are the same thing, I can tell you that they in fact are not.

86er · February 19th, 2009, 07:17 PM

lifter problems when collapsed put slack in the valve train, the tapping you hear when a lifter drops is the push rod tappin the rocker before it pushes it open, as much as they suck a dropped lifter is safer to have go wrong than valve float

lifter float is the same action as valve float the hydrolic portion of the lifter can't move as fast as the rest of the valve train. A collapsed lifter is just that a lifter that will not pump up. If you drop a lifter that's not lifter float, that's a droped lifter, when you float them you are floating all of them. If you were to drop a lifter odds are it would only be one, I don't think anyone has ever dropped all the lifters at the same time.

JBIGBOOTSY · February 20th, 2009, 05:33 AM

I allways thought lifter float was when the spring inside the lifter stayed compressed, just like when the valve spring stays collapsed. Im pretty sure your talking about pump-up.

Hey, Darrell what is lifter float?
