ok i also want to run the dodge on the track some, so thinking about sticking with 4.10s and a 66m turbo, and a auto wondering peoples thoughts on that and waht gear id be in, or if 4.30s will make it 1320?
 
I used that exact setup for a year.
Worked OK with the 35s, I went into 3rd gear most of the year but would recommend staying in 2nd gear.
If you have 33's then 3rd may be more viable.
 
if by 1320 you mean drag racing then yes if its not on the street 4.30's should work depending on the engine. but i think 4.10's would be a better choice.
 
Depends on the tires and how fast you plan on going.... How much power/wieght........ Are you going to run in the 12s,11s,10s? The best i have run with my truck is 11.47 et @114mph. I am gear limited. This is screaming at the other end and not making any power. I am running a small tire with 4.10s which doesnt help (245-75/16) but i run 101mph in the eighth dispite a 2.0ish 60 foot. After the 1/8th it just falls off cause im turning over 3200. Truck will rev to the moon, i have 5k GSK it just doesnt make any power there. And im not into over reving above 3200 when its not neccessary. (under load at full boost)
I have a problem cause i want to be in the tens and i need 3.55s. You will be fine with 4.10s as long as you are ok that you will be out of gear at the other end any faster then 12.0.
Taller tires will help.
 
Just my thoughts, i am not a competitive drag racer but have played around with it some and always knew that the best ET's come from the best acceleration from 0-660'(1/8th mile), MPH on the top end doesn't help much for ET.

Example, NGM's truck. i witnessed back to back runs of 11.0@117mph, a few weeks later they had made some changes, picked up 8mph and only dropped 1/10 on the ET when they claimed they ran 10.9@125.

I agree. It doesnt matter as much, and by the sounds of things, you want a medium between the two. Also, if your running a 66? you may be around 550-600 hp ? that should put a dressed street truck in the High 11s at about 114. You should be fine with those gears.,
 
I just want to have at the track local track is 1/8 mile but a few freinds run a 1/4 and i want to beat them with a pulling truck a mid 12 will do the job
