In my Cuda ..would jump from 28 to 29,5 for improve 60 ft and top end speed ... Now with 28 tires with 4.10 ratio my best ET is 9.79 at 142 mph ..1.48 60 ft .. 7200 rpm at finish line .. Look like too rpm ?? Because my power peak is at around 7000 rpm ... My goal is low 9s !!

Sorry .. Would jump to 29,5x9x15 Not 10

That car sounds awesome. We run a 29.5x10.5W R15 its a total of 13" wide and goes like hell off the line. but the best pass in our car was 10.30'S

The added weight May make it go slower ????

Time for Dana S60 (Strange) with chromoly tubes, spool and gundrilled axles.

I was waiting for these pictures to show up!

Iowan

If you stick with the 8 3/4, you need a spool and you should be changing the ring a pinon every 100 pass's or so (before it breaks).

I'd say it's time for the Dana, and you probably broke your trans also.

i have found in italy a Dana 60 OEM 1967 at good price , i can convert in 35 spline ... have power lock carrier

Hope it Works as Good as it Looks Raffa.....
Did you stay with the 4.10's or go with a 4.30 gear?
Hoping for the new best of a 9.50 for you....

Drag Pak

You might want to try that Caltrac bar in the lower hole/closer to parallel to the ground.

raffaplymouth

Hi... thanks for this info ....!! you think is better on lower hole ??? i can also move the spring eye location from lower to upper hanger hole ... let me know ...

Drag Pak

I think you have to test to find out what gives the best 60 ft. I believe there will be a difference from top to bottom, depending on how much axle - body separation you get/need and still dead hook.
