lighter motor - want stock ride height

I am going to be putting in an LS1 (aluminum block and heads) in my 69 x11. Compared to the 350 SBC (iron heads and block), the ls1 is about 100 lbs lighter. I want a stock ride height and will be running 15" rally wheels (no pro touring setup). I would like decent handling (better than stock), but will not be doing any road racing/auto-xing. I am thinking about the 6308 moog springs, being that they would make a SBC equipped car about 1-2 inches lower, so with the lighter motor i guesstimated that i would be back to somewhat stock ride height. will these springs suffice? Also thought about the 6320's and then cutting the spring to the ride height that i want.

Re: lighter motor - want stock ride height

This is rough, but I'd use the "spring rate" method,..for instance, take a stock height front spring with a spring rate of 300 lbs. It would take 300 lbs to compress the spring one inch. There are two springs sharing the load and since the engine weight is somewhat rear the two coil springs, the rear suspension is less burdened with the aluminum engine and the rear would ride slightly higher.

So, I think your front end height would only be reduced by 1/8 inch or so with the 100 lbs reduction in engine weight.
