Where should I start?

I have been building my car on a budget slowly over the last 4 years. I don't think the 6 cyn torsion bars are necessary because I have gotten my car to hook with a similar suspension that you are talking about with 318 torsion bars, SS springs, 90/10s up front and 275/60/15 M/T drag radials. Been a 1.66 60ft time pulling front drivers tire off the ground.

By the way this car still gets street driven A LOT.
