For those interested we installed an assortment of camshafts in the Screamin Eagle SE 135 crate engine. There is a full article & dyno charts on the FM University website here>> https://university.fuelmotousa.com/article/2045/
But as there are already sooooo many more people running the SE 128/131" packages out there looking and or changing cams...... 🤷♂️

Yes we did and we keep a file of each test. When I get a free minute to go thru and sort everything I'll post more info.

Still looks like Wood WM8-22X (TTS-100) rules the low end and Red Shift RS-468/548 rules the mid-range, to me. Regardless of engine size.
When MoCo shifts to all VVT, maybe this no longer matters? Of course, there will still be tons of legacy static valve timing engines out there for a long time.

I just spoke to Corey at Doc's and the only thing he said is that the RDRS adds some work and time for the person doing the tune, so maybe if that person doesn't put that extra effort into it, the tune could be affected. I can't say for sure, but it seems possible. Aside from that, he didn't indicate that RDRS hurts anything.
