572 RB Street motor advice?

IF I were to know how far I was going with the stroker 2 years ago, I probably wouldn't have let "the forum" talk me out of the GERST or RMS triangulated 4 link that I was intent upon getting. I know there are 9 second cars on leaf springs, and I like the Calvert split mono leaf springs and sliders with Assassin traction bars, triple adjustable Viking Warrior eXtreme street rear, double adjustable front shocks that I have, but I have to make room for REALLY wide tires, and I may have gone the way I had intended.
I'll cross that bridge, sooner or later, when I get to the tubs.
I’m going sub 5.50 1/8 mile/ 8 second quarter mile times on a 275 street radial and leaf springs. You don’t need big tires and tubs or fancy rear suspensions.
