Rear Tire selection

Makes sense to keep in power band. How about trans gear. Big thread here about 1.69 gear. Easier off line,might be able to add rpm at hit. Shift would be out little more which shoul lower rpme some in lights.
Next and what I would look at cam? If can use more power ? why not give her what she wants. Know nothing of your combo. If mine I would add 10* duration and move powerband up. Maybe look at compression if possible. Problem is means retuning combo if rasing power.
Thing is .2 can be easy if setup is off.If its tuned pretty good it can be huge to get that much.With the way you are running it looks to be tuned pretty well. Bad tuneup rarely runs consistent number.
Now this is from old blower guy who has not made pass in FED YET,so take it with grain of salt.

I hope my combo works out to be as consistent

Cody those numbers sound fantastic ! Please tell me more about your engine combo--I am very interested in what it will take to get that ET since we have the same car more or less
BTW I have a 4.22 gear with my MT 33's --My Nascar pal has lots of odd ratios --it is fun to look through his inventory.
I am running well but my little ole 355 CI is stuck in the 5.60's
I am very interested in what temp do you run it? Cam numbers, what type heads, etc
I have been told I need to get mine hotter before a run so just curious.
You have to be proud of that car and yourself--way to go!!

I don't have a temp gauge but the hotter it is the faster it runs.

I think my first time with no water and alky --I have been scared of baking it--what I have found is that I can even drive it back from the top end if I have to--I am sure I have not been hot enough at the line--so that is my next move to see what happens. May be closer than I think to some lower ET's--
Thanks for the information
