help with suspension on 69 project

[low69chevy]

Well have been trying to do some research on what I should do on my 69 c10 as far as suspension. I will be running a 370 w/turbo on the street and see some strip action every once in a while, on the street I'm going to be running 20x12 on 345/25/20 back
20x8.5 on 285/30/20 front

just cant decide on what to do as far as suspension want the truck to sit low tucking about a 1'-1 1/2' truck will mostly be on the street at the strip I'll probly be running a 28.5-29.5 slicks.

I was thinking of eliminating the springs and installing coilovers behind the axle and making some adjustable trailing arm how do you guys think this would work or what would be the best option want the truck to hook the best possible but I know thats going to be hard on a 345/25/20 street tire.

On the front also what would be the best options?

Thanks in advance
