alright winter has arrived, the mustang is parked, and the parts pile in my house is growing..but there are a few items iv been doing research on and im looking for a few 2nd opinions, one is gears, iv got stock ones with posi, now someone told me to go 4:10, and then someone told me thats a little much...and that the gas milage will go down the tube...*not to big of a deal, but id like to stay out of the gas station every 90 miles*...so im kinda stuck between 3.73 and 3.55...another one iv been doing alot of forum and magazine research on is headers, now i know this topic has been beat to death..but i know im going with long tube because....well long tubes just kick ass...i was having a hard time finding ones that were tuned..now is tuned headers the way to go? had my eye on a set of bbk full length nickel chrome plated ones on summit...but theres just so many choices...and i cant seem to find tuned headers that are nickel chrome with good flanges and stuff like that...thanks-
