Hey u Auto guys
Give me some TRACK advice here: Gary...u hv an Auto 
Info: I am running a 410 gear, Auto and a 3600 stall. I run thru the traps perfectly at redline in 3rd gear. My sixty foot is 1.54 but I am having to roll out of the hole. If I floor it from idle, nothing but a smoke show. Weight is about 3900 lbs without driver. Power is 465/450 tq.
Questions:
If I was to go say...373 gear, what will happen to my sixty foot ?
Would I then be able to floor it from idle to benefit from the stall ?
Any change in ET ?

Are you able to stab the throttle from idle ? That sixty foot isn't hurt a bit on yours. How much torque are you dealing with ?

yes. trying to get off brake as i bring up rpm to that good spot for me which is the 2200 to 2400 area. have hit a couple 0f times at2600 and the car launched real hard but spun just after i got going. probably if i dropped tire pressure just a little i might have got them to hook up

4500 stall here with 4.10 no reason you should not be able to hook at the track.
Are the tires shot? have you tried lower pressure? ET Street right? I used to run mine around 12.
I am running drag radials now.
going to 3.73 might be help some but not much...cheaper to go with a new set of tires.

Talk to some suspension experts before changing gears. I'm sure there is some tweaking you can do to help you launch harder and hook up. Don't go crazy and start swapping gears before trying out the easy stuff first.

I would have thought running the 4:10's, you would have run too high rpms, huh, interesting . . . I was thinking about going with 3:90's but heard that was too much.
I have 373 gear with 4k stall and cut high 4's - low 5's 60' - haven't figured out the best "flash point" yet . . I have just decked the gas and had a 1.51 60', so go figure.
sounds like whatever your doing (controlling the spin) by feathering the gas might be the best you'll be able to get without going to different. gears.
Are you NOT happy with the 1.54? I think thats pretty dag-gone good!
Sorry if I didn't answer the question.

I have watched Pitt run a few times, the back of that truck drops pretty hard, and could never figure out why it won't hook...the only thing I could think of and I have not looked at it is it coming back up too fast causing the tires to unload.. Other than putting some Lead in the rear.... Just mu .02 worth

If your rolling out of the hole and you are still running 1.54 60s with such a heavy vehicule. That is pretty good since you are probably at 4100 lbs. with you in the truck. Since none of the tires you mentioned seem to be doing the job. You might want to consider doing some rear suspension work such as different shocks and springs for starters.

Thanks for the compliment. I usually try to stay out of giving advice on subjects that I have little experience. Having said that, Ernie makes a good point if you are indeed unloading that light rear. You may want to stiffen the front shock setting to slow down the rebound or slightly decrease the rate at which it transfers the weight to the rear. A porpoising effect will cause the rear to unload.
Just my 1 cent.
