RE: We keep killing cams....
By Gary XL - 10/21/2004 10:58:27 AM; IP 153.26.176.34
I have a 64 390 with a solid lifter Crane cam set, using stock heads and shimmed factory springs that I built (first motor) back in 1985. I never heard about plugging oil port, etc, until I was racing C brand motors in the late 80's. The only problem I have ever had with the 390 is twisting off the oil pump drive in Wilcox Az when the shaft clip came loose and went through the oil pump. Still not sure how it got past the screen.
Anyway, I would look at the cam bore alignment and the lifter bore clearences. Has it wiped the same lobe each time, or is it random? Have the lifter bores been bushed? I have seen several thousands difference in diameters on lifters while building Chevy race motors. Had to stat miking bores and lifters and matching them that wasy due to the differences.
Hate to see anyone give up on trying to improve their combination, but after 3 cams it is understandable.
This thread, so far...
