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.

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)?

thanks

They will work fine and you will take a beating selling the ones you have...

Before you change the springs buy a set of good drag tires 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 The springs you have should work well with a good set of tires as long as the rear shocks are not topping out Did you clamp the front half or all of the springs?

I clamped the front segment. The shocks are the Mopar drag shocks, should be long enough, but a good idea to verify.
A "Good Drag tire" being Slicks? Or Mickey Street radials?

I'm curious too...what is a good drag radial?

Your mph says 11.90's, so get that 60' down to 1.65 or so and it should be high 11's all the time.

With 113 you have easy 11.80's with good hook. Get a good tire under it and like was said a good shock up front to transfer weight. Good luck , Ron

Currently I have Mopars' hi-performance handling shocks on the front, I have a pair of CE 90/10's I can swap out. I double checked the rear shocks and they are MP's drag shocks. I'll install the SS springs and look for a stickier rear tire. Elevens here I come!

Thanks,

Do you have a old set of front shocks that you don't need If so drill them at the bottom and drain them first(be careful,don't get any of that stinky oil on you ) before buying a set of 90-10 race shocks 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 Those shocks are good shock for both the strip and street, they are speed sensing according to Koni 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

Cab the CE's I already have. they are adjustable, 90/10, 70/30 and 50/50 I think. I can try these but if I'm not happy with them I may look into the Koni's, I like the idea of a good steet/strip shock better than a race shock since the car does see plenty of street time.
Thanks,
