71 c10 another front coil spring setup

Right now I have 1 inch drop springs and Summit racing cheapo shocks. I am planning on switching those out and working on getting better weight transfer. I mostly cruise the street but when I race it my 60 foot times are terrible. My front suspension is stock except for 2.5 inch drop spindles and 1 inch lowering springs. My rear suspension is lowered 5 inches with Summit racing shocks, shock relocators, and an adjustable tracking bar.

I have been stalking Super73's thread and reading other threads. I weighed my front using 4 corner truck scales and got approximately 1300lbs front left, 1075lbs front right, 800 back left, and slightly over 700 back right. The weights are with me sitting in it. Not sure why such a big difference between front weights.

Using Super73's weights for everything but wheels and tires for unsprung weight I get 332lbs. My wheels are tires are heavy at 49.5 pounds each. I come up with 1931 pounds figuring in the leverage ratio. My current compressed spring height is about 10.5 inches. I would like to stay around that height.

With Moroso trick springs I get a compressed height of 10.4 with 47180, 9.33 with 47140, 10.28 with 47195. Would I be better off going with 47180 and 47195 which would be about the same height I have now or would I get better transfer with 47140 and a 1 inch spacer?

I am also planning on a set of QA1 single adjustable shocks up front. What do you guys think?
