Re: Schubek Lifters
I knew somebody with a 220 horse 283.He ran 90-100 on the seats, and this thing used to break rocker studs.He did it enough that we wondered what went on here. Valvetrain separation caused it caused by the low spring pressures. I bought a set of Smiths lifters two years ago,and am just getting ready to use them with a steel billet Bullet cam, 7/16" rocker studs,Elgin rockers, and was fixing to set the springs at 200 on the seats,400 over the nose. Floating the valves smacks the base into the cam lobe, and the resultant impact shatters it. They don't seem to like mechanical lifter camshafts,either,and the same thing happens. I don't think there would be a problem in the event of rocker arm or push rod breakage, since the lifter would be up and out of the way in a hurry. Is there a better lifter to use with this steel camshaft,or are Smiths the thing to use?I like the idea of being able to change cams without breaking in a set of lifters each time. Any responses?
