Thanks ericnova72. I didn't think it would hurt anything, but I didn't want to start tagging valves. I highly doubt that this engine will ever see valve floatYeah, no problems until you bottom out the plunger.
Used to be a circle track trick to run flat hydro lifters just a hair off of bottomed out, so that oil aeration or lack of time to refill caused them to collapse and the engine wouldn't lose a ton of power.
Problem comes if you run it that way into valve float and the lifter pumps up, valves get held off the seat a lot farther and risk getting struck by the piston and bent during overlap.
Yeah, that is what I had always read and thought. Finding out that is not always the case.Aren't hydraulics supposed to be run at 1/2 of plunger travel or thereabouts ?
I have a set of the Morel #4602 hi rpm roller lifters in my 383 in my roadster. They were almost $800, but I know for a fact that they will turn 7000+. They have the .750 wheel. They are noisy as hell.I run a set of Morel tie bar hydraulic roller lifters in my Dart SHP small chevy block, and I paid like almost $900 bucks for mine several years back and mine has the .750 wheel size on them and I can say that my lifters are very noisy and for my studs which are 7/16 size and with the threads and stuff and according to my instructions it said to go about 3/4 to 1 full turn. I set mine at 3/4 of a turn and when you first start it up it makes a lot of racket and some more so then others but after it warms up its not as bad but I don't care about the noise as long as I know they are working right and there are no problems then I am fine with mine. I think its been three years now and have been pleased with them.
They also set to 3/4 turn preload. According to Straub the #5372's also have the .750 wheel. I didn't measure it.
I don't mind the noise in my roadster. It is a loud, obnoxious, in your face, scares women and children kind of hotrod. My coupe has an entirely different flavor Quiet mufflers, about half the horsepower, old man kind of car. It has a little bit of bark to it, but not like the roadster. The tappet noise just bothers me in that car.
