They will still produce the same cams and will pretty much supply them to the same customers sold under various nameplates.
Federal Mogul recently acquired the TRW automotive products division also.
If you purchase a Pontiac original muscle car grind like the 068 for an example, no matter whom you purchase it from it will be made by CMC.
Another interesting tidbit is that some time prior to 1990 when Crane and Wolverine were competitors Crane developed their own version of the Pontiac 9779068 (and maybe others) but advertised it as a computer enhanced version and not an exact duplicate.
You could try melling lifters..good ones the USA made ones not the Mexico made ones. If a Crane then check to see if the cams were ever made elsewhere ( Mexico ) or had service issues. but that was several years ago and now costs less to just buy a new Summit cam & lifters. With Crane there's nobody around to answer those questions. The more important view is who has a consistently good reputation and the product is such that you can check with the people that make it as well as take into consideration whom they supply their products to.
If you can't get concrete info then you'll either have to go custom if there's no other off the shelf cam with the specs you want or have the finished cam and lifters tested. Maybe smaller guys like Howards, Engle, Bullet, Schneider, etc. but doubt there are many making their own hydraulic lifters. I'm with other guys, if there's a good chance it will fail, just send it back and get one from another cam company ... There are options from others close to the Summit cam: Schneider: 30058 (284/294 224/230 0.510"/0.510") 45243 (284/290 228/234 0.512"/0.523") 64503LK (268/276 226/234 0.527"/0.547") This is a cam and lifter kit Isky: 135128 (280/280 224/224 0.490"/0.490") like the Lunati for your application. In the case of Howards, they have a strong Nascar and Saturday night racer base for their products. Crower has a reputation for quality and innovation as well as a strong racing customer base including Indy. As to identifying a crappy part from a good one by visual inspection, unless something is obviously out of whack, like you know an AMC V8 uses crowned lifters- then new lifters would rock when placed end to end ( lobe end to lobe end ) and flat lifters would be an obvious boo-boo.
Crane sold CMC to Federal Mogul about April or May of 1999.
Crane did not sell Wolverine to Federal Mogul and Crane still owns Wolverine.
CMC currently supplies many cams to the OEM manufacturers and holds copyrights for many OEM grinds. I'm doing a ultra-low budget build on a Ford 302 for my daughter's 64 F100. Afetr reading this, I'm probably gonna send it back. I'm doing a ultra-low budget build on a Ford 302 for my daughter's 64 F100. Afetr reading this, I'm probably gonna send it back. If you get mismatched lifters meaning some with plain sides and some with a groove on the diameter send it back. They have a tiny oil hole on the face to keep positive oil feed to the cam. ;) (Paul and Bill picked up the stuff at the border)Appreciate any history on this. You could try melling lifters..good ones the USA made ones not the Mexico made ones.It is true that a small percentage of cams sold under the Wolverine name are produced at the Crane manufacturing facility.To complicate things further it seems that certain grinds could be purchased under the Crane or Wolverine name that are the exact same grind, and CMC or Crane depending on the grind could have produced the cam.
I am friends with him, known him for a bunch of years, and he has no reason to steer you wrong. So if he says the lifters are "Hokey" I suggest not using them. If you are a racer type or simply are building a killer mill maybe adopting racer/machinist practice of checking cam and lifters for hardness and dimensions wouldn't be a bad practice with even the best stuff.
