I picked up a set of Moog #638 coil springs (listed for BB Camaro) for my 69 SB pace car. I thought these were a stiffer spring but after reading several posts I'm seeing that they are just taller, not stiffer. Is this correct? Will cutting them increase the spring rate? Thanks!

It's about 16" tall, if you cut one inch off the height, it will stiffen the spring by one sixteenth.
The first coil cut off will not stiffen quite as much as cutting one of the other coils because it is tapered differently.
This spring is not a good choice compared to other springs avaliable.

What spring should I go with? Realizing that I will probably cut any spring I buy in order to get the ride hight I'm looking for. You think the #6308 spring would be a better choice, David? This car is a cruiser not a canyon carver, but I would like to pick a bit more feel in the road without the harshness of super stiff springs. Am I dreamin? Thanks!

I think the 6308 is pretty close to ideal for a street stock type spring on a restored Camaro.
It will lower the front about 1" though, from what I've heard.
I have a friend who picked up a couple of plastic spacers that fit under the spring that could be used to raise it up a bit if too low.
Check with your local alignment shop for them.
