awesome guys thanks for all the help ..still really torn but looks like the 3.23 might be the better choice...i'm 75 miles round trip to work and drive her 3 times a week (weather permitting)
Again, which motor, how is the engine built, what rpm does the power drop off. My 340 coud use a larger cam, a 7,000 redline works good for 3.91's...so say 6,500 it be 3.55 and 6,000 I would use the 3.23
Gasoline isn't getting cheaper, $5 a gallon gas might be here soon, in that case 3.23 or even 2.94's you might want to get. If i drove my car 75 miles every 3 days, I be broke, lol
