Everyone has quarter mile combos how bout 1/8 mile combos?

right now 7.99 at 91 mph with a 1.80 60ft time spinning:D hoping for 7.70s or 7.60s soon

340 bored 30 over x heads stage 1 ported steal crank H beam rods 9.5 to 1 motor
 
Get your suspension dialed in, and you should be able to get a better 60ft and ET.

Here's mine:
904 manual VB
Dana w/4.10's
SS Springs
MP drag shocks in back
Competition Engineering front shocks
MT ET Street Radials 275/60R15

Times in sig
 
I keep mine set up for 1/4 mile, but I run 1/8 mile at my local track 95% of the time. The reason I keep mine set for 1/4 is simple....once in a while we have 1/4 mile races (like the Monster Mopar Weekend), or I travel to other tracks that run 1/4 mile. I don't want to have to over rev my car to compete...or worse, have to sit out a good race because my car is 1/8 mile only.

This is why I keep my car geared for 1/4 mile....Just my 2 cents.

410 stroker, pump gas, small solid roller, 750 carb, 727, 8" vert, 4.10 gear w/ 28" tire.
Times in sig.

[/IMG]Its a full car and a everyday driver. 360 .30 over stock eddy head air gap intake and 6 inch drag radials 60 ft 1.96 1/8th 8.43 84 mph
 
My setup is 440 509 cam stock 452 heads m1 intake tti headers ptc 9.5 covertor 4.56 gears 7.70s at 86 mph 1.68 60 ft with some tunning it should run in the 7.40s
 
I want to know how 7172 Duster and his buds are launching so strong! Those are very good 60 foot times. I am using a 3.91 and what are probably stock springs. Where would you guys look for improvements in the launch. Oh yeah, the converter is about 2200 RPM but works well on the backroads I drive at 45-50 MPH at 2200-2500 RPM so I would rather not change it.

Besides, I won't be putting in bars and the car is already too fast.

They have 5,300 converters with 5.13 gears going thru the traps in the 1/4 mile at 7,400 rpm
 
OK then, it's the converter. Nice launches but not practical for a fast street car. Thx.
