I am trying to get some weight and adjustability in the front of my B Body drag car. I hope this group can help me.
I have Magnum Force Upper control arms and HDK bolt on upper coil over mounts.
I have lots of shocks set up for coil over mounts from my dirt track days and I want to use those if possible. Easy ups, hold downs, 50-50, etc...I have the QA1 shock specs from HDK so I’m good as far as compressed/ extended lengths so I’m good there, but I do not think 3 in travel is enough for what I want to do. What I I need help/ advise with is a beginning spring rating. I want to know what spring I need to get stock ride height.
Does anyone know a starting weight rating, or a usable calculator? I have done a google search for a conversion calculation but evidently I am not smart enough to use them.

My thoughts are to remove the torsion bars and use the shocks/ coil overs to tune the front rise/ fall rates without changing ride heights. It’s worth a try I think.

Thanks in advance.
