I just did a LS7 454 for my street car this summer and wanted to stay with a solid flat tappet, looked at all of the blueprint LS7 replacement cams from Crane, Lunati, ect.ect. but was afraid of all the flat tappet cam failures so I bought a GM NOS LS7 3959180 cam and used the Crower solid lifters with the .024" EDM hole. Hopefully I won't have any problems when I break it in.

Some say the cores of recent are crappy and others say it's the lack of ZDDP.
Pretty sure there are only a few core suppliers, so one cam company is really no better than another.

a tech at comp told me they make their own cores because the ones they were getting had a large failure rate.i guess time will tell.

P55 cores are made by Engine Power Components, wonder if they are still around. Been 8yrs or so since I;ve gotten a flat tappet.
