I dont think i would want the stall or gears (lower gas mileage) since its a daily driver... What should i be runnin if i already have K&n cai, pacesetters (stock y, no cat, flowmaster), b&m shift kit (auto), ss wheels(pretty soft rubber), jet chip stage II, and a 52mm tb??

I would say mid 13s..

get yourself some kind of cat back or true duals... the flowmaster sucks.

but i mean if your looking for gasmilage buy a civic.. you have a hot rod not a grocery getter.

seriously.. just save up and buy some 1500dollar beater for a daily driver.. or be cool like me and buy a bike

If you dont want to lower MPG any and still want power I would get a nitrous kit. BTW I have 3.73's on my dd and in the city my mpg did not drop. Only on the highway.

I also saw in an earlier post that you are looking at a cam. If you are looking at a cam than mpg concerns are out the window.

I had the Hot Cam Kit in mine, got high 12.5's with just the Cam, very mild Head work, Tune, 3.73's and a 2000 Stall. I had full Intake/Exhaust mods as well.

Cam Kit came from Summit, comes with everything. It comes with LT4 Springs, they are barely enough to sustain the Hotcam when you put it in and with the 1.6 RR's. I would look for a .600" rated spring for any Cam for a LT1, you will be good for a long time with that.

Start with a small cam that increases power in the stock rev range, (Crane 227, Lingenfelter 211/219), and throw the biggest heads you can afford at it.
