Hey Al, sorry to hear about your motor. Are the bearings damaged from debris going through or from wear? When my 455 cam went the oil pump sucked all the crap through and went through the oil filter bypass and got everything. When our race motor went, the bypass had been plugged by the builder and the carnage stopped at the filter. We now have a half set of comp bbc sr lifters that haven't wrecked a motor yet if anyone is interested. The lifters didn't have very many runs on them but they were worn out. We now have crower severe duty sr lifters with high pressure pin oiling. I believe they said they were good to 1000 psi open pressure. We will be taking that motor apart in jan. to check it and I'll report on them then. Neill
