About $100 - $120 on the cam core upgrade to billet stock. Another variable cost is the distributor gear upgrade to whichever version you prefer? Some offer the press on gear option at $75 additional, others more $, and some do not even offer them at all. Then there's the lifter options as most cam manufacturers will spec their premium roller lifters to match the cam core and that can add significant cost atop the camshaft upgrade?
One last thing to consider is the delay in lead time for having a stock grind cut on billet stock? If a given street grind is on the shelf in a cast hydraulic roller and you need it on billet, be prepared for delays to have it queued in for a custom grind. I've been through all of this with Crower, and Lunati before and the worst possible time to ask for this is in the off season while all the racers are building new motors. Myself, I'm all for billet when it comes to solid roller grinds, high spring rates or high lift/duration grinds, but for street grinds under 575" lift I still think the cast core on a roller setup works fine. A good set of mid grade roller lifters and spring rates under #375 and I'm totally comfortable. Just an opinion but it's as much about break in and lubricity as it is about core hardness right? Gotta think that a lot of failures on cams is due to lifter selection, valve train geometry, and setup by the end user me thinks. ![]()

lmao...been there done that
![]() In the past 12 months I've ordered a Crower Hydraulic Roller, a Comp Solid Flat Tappet, a Lunati Solid Roller, and this current build is a Crower Solid Flat Tappet. Got the full gambit and looked at a lot of grinds before settling on these 4. Heard every sales pitch, had a lot of advice and learned a lot about cams.
