Stroker specific cams?

I have made such mentions before (I don’t know if I did in this thread, doesn’t matter....) and have stated why there is a good use for, and the reason behind a split duration cam. Before or After your heads are ported, they should be flowed to understand the balance between the intake and exhaust ports where you should then find the balance percentage ratio between them both. Once this is known along with the rest of the engine package, you can determine the amount of split you may want to run effectively.

It is certainly, IMO, that running the maximum amount of lift or radical lobe as per your lifter diameter isn’t necessary for every engine. Nor is running a split duration cam always needed for an excellent result. The need to take maximum advantage of every aspect of an engine isn’t always a warranted or must do and use venue to take. Taking this road can lead to vale train issues like noise, early spring replacement, etc....
There is also the characteristics of the cam itself which you may not like. Often I have seen fellas replace a cam on that alone. Mainly due to the car being driven very often rather than raced. If your exhaust ports demonstrate excellent flow, a reduced exhaust duration will not hurt a thing.

Good article link. Glad you put it up. Which I’m now going to read...LOL

(Edit; That was a good (& quick) informative read.)

I have been discussing this whole cam selection with another member here via PM's. We went over the combination in fairly good detail, and he came up with something similar to the Jones cam, without the IR lobes. I might be able to get more power out of the IR's, but I also will be able to use non proprietary lifters without fear of valve train wear issues. The one thing that once again came up is the use of a single pattern cam. I found an article from Engine Builder Magazine mentioning that single patterns are becoming more prevalent as the newer generation of heads have better exhaust flow then those of the past. Thereby, decreasing the need for split duration cams. I know that this may have been covered in this thread somewhere, but good to see it elsewhere. It is a basic article to a lot of folks here, but good information for those of us not as well verse in these things. Link provided below.
