We fired our motor for the first time today and what happens? A lifter ate the lobe . The only thing to do ,take the motor apart again .No further damage was evident .What can we do to avoid this again.Is the schubeck lifter really as good as they say?I am thinking of buying a set if this ends our trouble. Spring pressure is 200 seated 400 open. Later .. Hans.

Hans,

Which cam and lifter combination did you have? Im just curious on this 1. On the Shubecks, I cant vouch for them yet. Once Dad get to read this, Im sure he will be able to tell you more.

the big advantage is that you can run huge valvespring pressures on almost square lobed cams but they are not cheap

Hans sorry about your missfortune. The Schubeck lifters have a ceramic base and are almost indistuctable. We are a dealer for them and we also use them.

My cam guy has been with Comp cams from around the beginning. I have a friend that had this happen to him recently. I was told the ONLY way this can happen is that the lifter stopped turning in the lifter bores. Either something got in the lifter bores or its out of round. More than likely its a block problem.

Unfortunately you will probably end up pulling he motor and need some work done to the lifter bores.

When the cam lobe was eaten up, all that metal went somewhere in the motor. You will need to pull it apart and clean all that mental out, or you can end up with more problems.

We will take the motor apart completely and clean it from any metal residue. We are going to take a step back and use our old comp cam and lifters, which is less aggressive and runs with less spring pressure. 140 at the seat. Revs easy to 7500 rpm. A new carburetor and ram air intake will help the et. Hans.

Yes they are Jay! Especially when the rules require a flat tappet oem style lifter.

The idea that you don't require a break in period, and the stress that goes with it, is worth the price alone.
