Get the 300s, maybe stiffer. I have 275 springs. At stock ride-height the bottom of my spring is too near the top of the shock. I have an aluminum block.

Yeah I'd go with 325s or 350s. I've seen a lot of iron block cars sag in the front with 300lb springs.

Give us a call. I can spec you a spring and a set of shocks. We use 325lbs springs on iron block BBC only.

I have an iron block LT1 car with 275's. I have some regular weight reduction up front, but I have an aluminum single plane intake/elbow instead of a plastic LSx style intake so i'm adding a little there as well. My car sits fine.
