I actually have two of these cams and both are NOS. The first is just the cam and card while the second is complete with Crower springs, pushrods, lifters, etc. Running a # search on the Crower site returns zero results. My next thought is to call them and ask for any archival info. However, before I do that, perhaps someone here has experience with the 05202 series cams? Both are marked 1 - x594 - H. The H I assume stands for hydraulic. From what little I can find online I believe they were produced in the mid 70's and are part of the Crower Corvair "Killer Cam" lineup?
Many thanks in advance for any helpful info/insights

Im not really sure yet Ken? I’m thinking about letting one go but need to determine the best application for them. If they are more for racing and less of a street cam then I’ll probably sell one or possibly both. I know Bob (DrYenko) mentioned he was familiar with the Crower 5201 so perhaps he’ll know a thing or two about these?

These cams are split duration with more on the exhaust.
Durations given are best for a near full race engine with fully ported heads and larger exhaust tubes, to make best power.
The 105 degree intake / exhaust overlap is also indicative of a full race cam, as this will make for a lumpy idle.
Stock cams have this in the 112-114 degree range
That won't drive very well on the street.
But this cam would make a nice Corvair vintage road racing application.
Cam should be dialed in and installed with about 4 degrees of crank timing advance to help mid range power.
Interested in one of these for a upcoming Yenko Stinger engine build if you decide to sell one or both.
For a street application, something like a Isky 280 makes a drive-able engine with more power than a stock 140 cam.
Be careful with the regrinds sold today as they have been shown to have lifter " issues ".
Hope this helps.

Bob is spot on. That is a good vintage Dp type car cam. Crower made the 5000 series cams in the early 70's. I used the 5201 in street cars. It was like the older OT-30. It really performed well. I still most likely have an old Crower book somewhere with the 5000 cam lineup shown.

If you were to compare cam cards, in a apples to apples format, keep in mind the Crower degree numbers are figured at .040" of tappet lift. The modern standard is .050".
Still a nice spicy offering from a giant in cam grinding.

My mistake TYD…. I thought it was Bob that said he had used the 5201.

Many thanks everyone for the helpful info. It appears I have a couple of fairly rare (but limited applications) racing cams just sitting around on the shelf that probably need to find new homes? I don’t see myself doing any racing builds anytime soon nor utilizing these cams as they were intended.

The first is just the cam while the other is essentially a complete setup (cam, push rods, lifters, double springs, etc.

For those of you that first expressed interest in the cams, shoot me a reasonable offer via pm. I’ll review those offers first and get back to you. I can also post a few more pics of the complete setup if necessary.

Don't forget to entertain trades of your Crower cams for a cam and valve train parts that you can use in a street engine build. That's what I did with Ken Hand with a same vintage OT-30.
