damn. Where do I begin. So....
I ran the cnc mill, cnc lathe, the hobb machine and the straightener. Depends on what was going on, I might be cutting billet blanks out, loading the blanks in cnc mill, cutting the empty spaces between the lobes and journeys, and then drilling and tapping the holes for the cam gear bolts. Then I may be in the mill room, putting the blanks in and cutting the rough cut lobes, changing bits when they wear out. Or cutting the gears on the cam (depending on cam). And then they get sent off for plating and heat treat. Then I got to use this huge electric hydraulic press that you spin the cam with dial indicators and straighten it out. Final grinding finishes straightening. What was title? Umm, didn’t really have a title. Just did what I was told. Lol.

when I was there, we mainly did the cores for comp cams. Mainly sbc, some ford and bbc. I don’t remember how long I worked there. It was just a blip on my radar at this point.
btw, there was no quality issue with their cams. The only issue I have with them is if you call and get a recommendation on a cam, you will likely get something a bit smaller than you desire. If you spec your own then you should be good. I just prefer the off she shelf grinds that summit and Texas speed offer. I don’t like BTR cams either. The one I had just didn’t work well and was harder to tune than it should have been. It killed too much idle torque. Personal preference.

I will say this much... When I spec cams for others, if I get stuck on a fine line between two or three cam specs, I will usually err on the slightly smaller one, unless dedicated racing. The reason is that for most people, an extra two degrees isn't going to be noticeable SOTP for power, but the PITA factor will be. It's like shopping around for breast implants with your girl. There is no subtle change from just right to too big. they're just suddenly too big and you don't like them. Slightly smaller, still looks great and lots of fun. Same with cams. you often won't miss the extra two degrees, but you will absolutely hate it when it's too much for your tastes.
So I can understand erring slightly small in some cases. it's especially tricky, because you have to avoid superimposing your own preferences onto the customer. My personal tolerance for cams is pretty high. Current cam in my 440 is 256/270 with .747/.729 lift. And I think it might could take more cam.

Ex employees are a lot like ex girl friends too. No matter how good of terms you think you leave on they rarely have anything nice to say about you. Lol. Most people would think a 232/248 116 lsa on a 5 degree advance is a little large for a procharged 377, but I love this thing.
I bet @CAMMOTION PERF has an interesting side to this story. I have a feeling popcorn is about to be needed.

When you say...I used to work at cam motion and I’d recommend someone else like summit or Texas speed...it’s easy to see an implicit meaning or underlying tone there. He was more straight forward about btr by saying he doesn’t like them though.
I actually have parts from summit, tsp, cam motion, btr, as well as others so it isn’t really any of my concern just something I picked up on.

I much prefer Cam Motion over BTR, but that's just me. The following 3 users liked this post by ddnspider:

And then you asked him what exactly he did there and he was explicit, if not overly forthcoming, with his roles and responsibilities. There's about a million reasons he could prefer one over the other. I'm simply saying he didn't share some horror story so if someone wants to jump to conclusions from basic information.....welcome to the internet I much prefer Cam Motion over BTR, but that's just me.
