Hey everyone. I just bought a 95 Firebird formula with the lt1 and have a question about valve springs. According to the previous owner when he bought the car it had a cam in it but I am unsure if the valve springs were replaced with upgraded ones when the cam swap was done. I don’t want to run the car like this if it’s still the stock valve springs and risk breaking a spring or damaging something. Does anyone know if these springs look like they are aftermarket or stock? Thanks in advance for the help.

I'm no expert but those look just like my stock springs in my 95 lt1, pastel green stripe and all.

Thanks for the reply. Yeah I figured they didn’t look like anything special. I guess springs are in my near future.

The real question here is; What cam was installed & what are it's specs? And how many miles on engine?

If someone installed a mild upgrade cam, factory valve train should be fine. At least with mileage under say 120K. But you should be able to start engine and idle and tell if it's a mile or radical performance cam in there.

And this brings on another problem. A high performance cam change needs to have the PCM tuned for the upgraded cam so fueling will be correct.
