Re: camshaft won't last wtf !!!!!
I don't think it's a lube issue. The cam is lubed mostly by oil thrown up there by the rotating assembly. The lifters put oil up the pushrod for the rockers, etc. but I don't think that has anything to do with lubing the cam. I am inclined to agree with the spring/guide/something mechanically screwy opinions. I doubt you could get unlucky enough to mess up the valve adjustment on the same valve twice. I also agree completely about the roller cams. I have been running hydraulic rollers with great success. For my flat tappet 4x4 I run rotella diesel oil in it because it has the zinc needed for the flat tappet. However, they are reducing it in the diesel oils too now . The valvoline racing oil still has it for a more reasonable price compared to some others.

No more dragtruck for me. I'm building a new ride though. It's a '71 fleetside, 400 sbc, 700R4. Working on it now, finally. Soon to have Edelbrock Pro Flo EFI, Vintage Air, 1 piece windows, buddy buckets, etc.

Best pass with the old dragtruck:
5.32 @ 131.6 mph 1/8 mile w/ a 1.25 60' Fogger/Plate 2003
Best pass with the street 406 hydraulic roller motor w/ mild plate tuneup
5.93 @ 114 mph 1/8 mile w/ a 1.29 60' 2003 or 2004
