3.73 3.90 4.10 ?? th350 not a dd
hey guys in looking to do a gear swap on my car. i have th350 with 3600 stall. rest of my mods are on sig. i will be mainly running 1/8 mile, but would really like to finish the 1/4 without hitting the limiter. i have two sets of tires i have 26 tall and 28 tall tires. don't use the hyw much, when i do drive it. so hyw is out the question. im highly thinking 3.90 to be in-between but if i could go 4.10 would be nice. the car spins to 7k
thanks in advanced
i look on the stickies but there was all on a4 trans

You need a good guess of your 1/4 mile MPH, and an idea when your engine tops out RPM wise. Then you need to factor in the tire height. For lowest 1/4 mile ET you should be just above the power band in the traps. Like at your 2-3 shift point. There are all kinds of drag race calculators on the web. Google and try them until you find one you like.

He wanted gears for the 1/4 mile
Spool on the street depends on what you comfortable with. I have a tubbed 73 Nova with a spool and it's a street car. Also has 4,89 gears. But I knew what to expect before I did it.

i don't get this!! i might just go 3.90 and see what happens. i wanted to go the tallest gear possible and not run out of gear at the 1/4 with a 3 speed.
about the spool i read up on people braking there axles from the tires chirping when they turn. im guessing that's out of the question or were they wrong? the car will see lil street use ill only drive the car for one hole week just be cause of excitement the first week out, but then it would be from my house to the track and back. maybe a hangout here and there beach maybe once a month.

When you're between your stock gears and going 4.10.....go 3.90. Especially since you're thinking about going from track to highway, but definitely look into strengthening the rear end with a 9" or 12 bolt.
