Front End Unsprung Weight

For a streeter,1.03s are never too big...... ever. Unless maybe for an all-aluminum 6-cylinder. Or unless you leave the teensey weensey stock springs in the back. But you're an engineer, you would never do that.
However, your engine might be too small for 1.03s,lol.Unless you put some serious gears in the back. Cuz if you can't steer with throttle, that just takes all the fun out of them.
IMO 400 ftlbs should do it. From idle to about 6500rpm. Hyup that sounds about right. Yes I'm kidding. But wouldn't it be great!
