Ok well after reading all of these posts lol some getting off subject. lol I have my new plan, to go for 3.73 ( Did i hear someone say my stock gears are 2.73 by the way?) and im going to look into a PI Swap

you should have 3.27s look at the tag on your rear end

5.0 85 GT

yea you have 3:27s stock which are adecent all around..intended for hiway and good gas mileage...if i were you, they way you sound right now..go with 3:73's...i have 4:10s and i love them..but i got no hiway...i am at 2300 rpms at 60 ish mph..not soo good..but do 3:73's, pi intake, o/r midpipe after you go through emissions and a nice set of mufflers....and then do a throttlebody and plenum..and go have fun
