Spring experts ? Oem mopar spring identification

[ValerianMagnum]

I bought an engine and the guy wanted me to sell those springs... he bought them with some spare parts, they are painted dark red and are not double springs and he thinks they come from a 340 6 pack or so , looks like factory and not aftermarket, anybody as an idea ? ( ****they were placed in a comp cam box ahahaha )

I remember I had BB springs that were red. Single springs, no damper.

Paint stripes could have been added by anyone. Only way to be sure is to test them on a valve spring tester and see what their rate is.

The springs I mentioned in post #2 were painted red, not a red stripe.

He told me that they were a bit less stronger than comp cams....but stronger than stock ones...so i think a 490 or less cam will be alright with these , i hope so
