After almost 6 months of looking I finally found and bought the 68 Camaro I wanted. The previous owner lowered the vehicle about 2 inces in the front which has lead to way too many clearance problems and I want to return it to the stock look. Does anyone know how different the springs in a 78Z28 are from the stock ones in a 68 small block?

Thanks,
Steve

The springs are too soft in rate and probably the wrong height.
The later spring is also a larger diameter.
early was 5" OD, second gen was 5.5" OD.
The best drop-in stock height spring is a Moog first gen Z/28 spring #6308, it's around 390 lbs rate, stock was around 327 lbs.
A 550 would be ideal for good street handling, 600 to 700 for wide tires and agressive driving/track or autocross.
You could also buy a plastic spring seat spacer that would raise the car back up. It would need to be approx half the thickness of the needed height change due to leverage over the spring.
So, for a 2" height change, a 1" spacer would be needed. This is just a guess.
I'd really recomend a stiffer spring than stock if at all possible. Also good shocks and swaybar.
