Yes, they probably would......but then you have to wonder why if they are using some other well known cam, why isn't that company the one giving out free shirts. I'd wear a free one..........
Free shirts, caps etc. would be good. Selling shirts etc. with the company logo makes far less sense to me as a customer, the company wants me to pay for advertising their brand for them? That's not how advertising works.
That's exactly how it works. They get you (the consumer) to buy a product with their name on it, then you're advertising for them. It doesn't matter whether it's a shirt, hat, intake manifold, valve covers, air cleaner, wheels, etc., the #1 reason to have the manufacturer name visible on it is to entice others to buy the same brand. When you see people on those race shows on TV wearing a shirt with "Precision Turbos", "Isky Cams", etc., it's because they're in a partnership with the company. That person wearing that shirt is getting products or discounts in exchange for repping the brand. It's a business arrangement. If they can get the consumer to buy a product AND then effectively advertise for them, that's a double win.
For what it's worth.....45 years ago I installed a Crane cam in my 327, used their break-in lube and did the required 20-30 minute break in. In less than a week the cam went flat. I was pissed! They sent me a new cam and lifters at no cost to me and after taking the engine back down to bare block I had it cleaned......the new cam worked as advertised....
I had issues with an (actually two) Edel---ck cam. Since then I have ground their name and any other identifying marks off their aluminum intakes (which were purchased used). I refuse to advertise for a company that I have lost faith in.
Regrind? Yes. I put a "known good" used cam and lifters in the most recent engine I built (this year.) Running, driving; so far, so good. Glad I did it. Engine before that (last year) I put a reground cam in it, measured it up between centers and it was spot on. Run ins on the run stand all good; fingers crossed. Need to poke it in the car and drive it.
