Took the car out to Lapeer yesterday for some T&T. It ran good, a best of 12.35 @ 113.32 and that was with a 2.0 60ft. Good MPH for this combo,I need to work on traction first then fine tune. ![](/ubbthreads/images/graemlins/drive.gif) The Car: 73 Challenger 416 stoker 10.5 cr. Comp hydraulic 250* with .525 lift M1 single plane w/holley vac secondary 750 Hooker SC 1 3/4" thru 2 1/2 pipes to dynomax super turbos exiting at the axle. 727 with a 3500 stall 10" convertor to 4.30 gears on BFG 275/60x15 drag radial @18psi. I have the rear springs clamped but I'm thinking Super stock springs and a Pinion snub should be the next step. the car weighs in at 3780 with me in it(yea I know get out and lighten the car 200lbs). I have a set of e-body SS springs rate for 3300lbs. do you guys think these would be worth a shot or should I sell them and pick-up Higher rated springs(3600 or 3800)? ![](/ubbthreads/images/graemlins/3_2_116.gif) thanks

Before you change the springs buy a set of good drag tires ![](/ubbthreads/images/graemlins/thumbs.gif) As far as a pinion snubber don't waste your time or money, a good set of springs will never let the snubber hit the floor ![](/ubbthreads/images/graemlins/scope.gif) The springs you have should work well with a good set of tires as long as the rear shocks are not topping out ![](/ubbthreads/images/graemlins/scope.gif) Did you clamp the front half or all of the springs?

And a good set of adjustable shocks to get the car transfering weight. I bet the car will run 11s with a good setup...not bad for Lapeer ![](/ubbthreads/images/graemlins/wink.gif)

Do you have a old set of front shocks that you don't need ![](/ubbthreads/images/graemlins/devil.gif) If so drill them at the bottom and drain them first(be careful,don't get any of that stinky oil on you ![](/ubbthreads/images/graemlins/tsk.gif) ) before buying a set of 90-10 race shocks ![](/ubbthreads/images/graemlins/Twocents.gif) I have tested a lot of front shocks on different cars, I now have the Koni SPA on the front of my street car ( BB powered 1971 duster)that runs 1.43 60 ft. times on M/T ET Street Radails ![](/ubbthreads/images/graemlins/thumbs.gif) Those shocks are good shock for both the strip and street, they are speed sensing according to Koni ![](/ubbthreads/images/graemlins/thumbs.gif) BTW, if you want a set you have to buy the ones for the B bodys as Koni doesn't list them for A bodys like our cars ![](/ubbthreads/images/graemlins/shruggy.gif)
