tires and gears

need new tires for season and maybe change the gear. what do most of you run right now. presently 4.56 with 31 tall tire to go with the 540 with 4500 converter or should I leave it alone and not change for 8th mile track?

I run my car at both 1/8 and 1/4 mile tracks and don't change anything including the tune up, 6:80 in the 1/8 and 10:40 in the 1/4 My car is a street and strip car, not a dedicated race car I have tried three different rear gear ratio in the car with no other changes, 3:73, 3:91 and 4.10 with the same size tires, 30 inch tall radials. car didn't vary .10 ET in the 1/4and .25 MPH between all three ratios My motor is a 4.300 stroke 400 block that is 518 C.I., low compression on pump gas motor only

An option, find the correct gearset that works with both tall and short slicks, we used to run the smaller dia in the 1/8 the larger in the 1/4..but that was a long time ago.

Hi,Jnkgal! I would go with 30"-31" tire again,and keep the 4:56 gear...if you're revving 10% over your peak power rpm in the 1/4 mile! BTW...NICE SELF PORTRAIT! Looks like you're making a wise choice in professions,also! My wife's been an RN for 20 yrs...VERY GOOD job security! Good Luck with your schooling! Remember this fine work of art you did for me a while back??? Really appreciate it!

JnkGal...You still out there???

Just replace the tires UNLESS your over reving it on
the big end... what rpm do you cross the line at...
if its in the ball park save your money... I dont change
anything between racing 1/4 or 1/8... its bracket racing

Things got enough torque to pull fire hydrants outta the ground. I would think 4.10-4.30 as is in the vid. And roll through the water before burnout..slings water up only to fall back on the tires. Driving around the water is a good idea too.

here is a better video

and this one where I am hesitant to post cause the sound is bad. This is a sony camera this time and it does great picts and video but sound is not so good. This car sounds awesome in person!
This is us riding together on Co Pilot nite at union hill 2008
2008 CoPilot at union hill

the one video we took co pilot at union hill we had to short shift to stay under 850 or get kicked out of that class

id kep the 4.56 and go with 30 inch slicks, unless you out of motor at 1/4
