Who here knows definitively? Who has done metallurgical analysis of either brand? And, is it a proven fact that Ferrea actually manufactures and machines their valves? Where’s the stainless sourced from? Lots of companies (in general) import and machine (or finish) as we all know.
Maybe Ferrea does it all, or maybe just machines a nice finished imported valve?
I don’t disagree. I do have more faith in Ferrea as a company,to stand behind their product in the event of a failure. They also have years of R&D in Racing and performance, whereas SM is just ripping Edelbrock off.
