We are dealing with a 445 FE (the same wear appeared when it was a 390 as well).
It has
- C8AE-H heads.
- Erson Rockers
- Crower 280R "Street Roller"
- Crower 280R HIPPO Lifters (same part number as a LIMA motor)
- Crower Springs - 68385-2 390/405 open
- Smith Pushrods
- 90 Holley Jets in the oil feeds
I am having issues with rocker arms adjusters wearing rapidly, i had told smith to drill the pushrods for oiling in case i wanted to do that, perhaps that was a mistake. The adjusters wear fairly quickly to the point they have a nipple matching the pushrod oiling hole. (we are talking 1000 miles or so) I have used, the Erson, Smith Brothers and Harland sharp adjusters with similar results. The Springs are the ones recommended for the cam, and are not in coil bind, i measured the pushrods way back when and don't remember the length.
I am considering:
- Rechecking valve train geometry
- Reordering pushrods without oiling holes
- Decreasing Spring Pressure (what spring) Maybe Comp 924-16 347LBS/in
- Putting a 300 6 in it
- Putting a Coyote in it
- putting a Howards C6OZ-6250-B.in it
Only sorta joking with those last 3
Any ideas?
