I just purchased a set of eibach loowering springs for my 72 for a small block. Just came across a real good deal on a big block 396. I have read the weight diff is around 100 to 150lbs.How much more would that lower it and would it be a problem.Thanks

Eibach says they drop the front 1.3", but mine is so low I can't roll a floor jack under the front cross member, even with a 3/8" spacer. This is a small block with A/C.
