Anything that increases hp, lol.

Force = Mass * Acceleration,
So make more power or lose some weight. I would recommend FTRA or SSRA if you don't have one yet. and it doesn't get in the way of your tranny cooler.

LOL I added the pulleys hoping to get some extra mph but nope not a single digit or even a fraction of a digit. My best mph is 115 and I can't even budge past that

And no NOS! I'm going all motor baby!!

a resleeved block setup for up to 454 cubes with forged internals, worked LS7 heads, LS7 intake or custom, with a little 2 stage nitrous system.

or

a 402ci (stroked) LS2/408ci iron block with forged internals and a intercooled GT-47 turbo or ATI F1 supercharger.

Both of those will SERIOUSLY increase your MPH.

alright since you just want to increase your mph's and your not talking about how fast you want to get there....

just go get some higher end gears.....2.30s....take you forever to get there but youll have a pretty big top end....i have 2.73s right now, my car can hit the cut off and isnt even near the rev limiter

Heads is pretty much what I've been hearing. What brand do you all use or reccommend. There so dang expensive though LOL

I love the look of the fast intake, absoutely love it. But I spent $300 on my LS6 and don't want to sink another $1000 into an intake unless it's really really gonna help....even though I do LOVE the way it looks; with the red fuel rails and red injectors and my red wires...umm now that's sexy!!!!!

He is a SHE FYI. You can get your Fast 90 and sell your LS6 for $300. You pretty much just spent only $700. With heads and better intake = big gains on MPH.

I hear you can get some good gains off of Patriot heads and those aren't as expensive as afr and others, you could always get your stock heads ported too if there's a machine shop that you trust nearby, I see you've already changed your gears to 3.73's so I don't see any reason for going higher, unless this is a track only car and your not worried about sucking down a lot of gas then maybe 3.90's or 4.10's would help, honestly I have just started looking into head's so my knowledge and research is minimal, I've just finally decided on the cam set up that I'm going to use, definatly check out the other forums on here, there is tons and tons of great information on this site

You are out of your mind if you actually think 2.30's will increase her MPH in the 1/4. She'd be lucky to trap 110.

Try changing your rev limit up 200 rpms and reprogram your shift points to take advantage of the extra r's.
Almost free!

The obvious answer would be to add power, e.g. heads, bigger cam, bigger intake. I'm looking to increase my trap speed also by way of 3.73's. With your 3.73's you could have your tuner lock up your TC at around 100-105 or so. At that speed you should be past your shift extension and won't hurt your e.t. Apparently thats harder on the TC/trans but it will increase your trap and I am also considering it along with the gears.

Hope this helps.
