Re: The manufacture of valve springs...

Agreed, the older engines used much lower spring seat pressures. So springs generally lasted, longer, if not almost indefinitely.

As for source of materials... ...steel from India is big now. But they have had far too many bad experiences (failures) with it and will not use it. Now granted, it was probably with higher spring pressures items. The Dodge Hemi of '03, '04 had some spring and valve issues. ...don't know what they used and from where, or if the design changed in '05.

I'm just starting to look around and do some research. I will check with the PPG to see what they have available.

As I said I am interested in getting into the manufacturing/supply arena. I also have some contacts in the plastic industry also. ...repro knobs anyone!? I've spent 20 years in front of a computer during the week, and under a hood on the weekends. Wait, will this be any different?

Thanks,
