I wanted an engine with hydraulic lifters to cut down on valve noise. The engine does look to have been rebuilt, but it has a code of F55Z which tells me it's from a 55 car and not hydraulic lifters. The rebuilder installed hydraulics, but the seller says he didn't use the engine because he didn't like the valve noise (quite understandable). Is there any way to make hydraulic lifters work properly in a non hydraulic engine? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | That's right: Z = 1955 car 235 with standard transmission - mechanical lifters
You'd have to get the block drilled to provide an oil journal for the lifters (so I have heard).
You might want to put mechanical lifters back into the engine? | | | | | Joined: Feb 2004 Posts: 29,777 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,777 | Is there any way to make hydraulic lifters work properly in a non hydraulic engine? Maybe- - - -if the block has the drilled oil passage from front to back through the lifter bores, the solid lifters can be replaced with hydraulics without a problem. If the passage isn't there, find another block. Jerry

If so wouldn't he also have to change cams.

The hydraulic cam has very short "acceleration ramps" that stack all the parts of the valvetrain together before the valve actually starts to lift. A solid cam has a longer area of slow lift that corresponds to the clearance specified by the cam grinder.
