gear question unfortunately

[13DIB5.0]

Ok so got a Paxton m6 car I spin to 7250 and currently have 3.90s I'd like to swap to either 3.31 or 3.55s. My street tires are 27.7 inches tall and drag setup is 28s. I do mostly 1/8th mile and rolls from 20 40 and 60. With the occasional 1/4. Just trying to pick the best option

3.31's, will do a better job at keeping you i the powerband, the 3.55's will have you close to shifting to 4th [or lifting] on the 1/8.

3.31's with 28" tire should trap 106 @7200 in 3rd, 135 @7200 in 4th.

If 331s will keep me in my power band (making it faster) then that's what I should use. Wouldn't it make it feel worse on the street though?

With all that power its fine as long as your tune has faster throttle response than stock you wont find it slow.

Strangely i was trapping 127 with my 3.73 then i switched to 3.31, upgraded my block and added 100hp and wt but my trap speed went down to 122.

So i dont know about that 132 trap mentionned at 7200...!
