    I understand the sentiment but, for me, its not about fuel economy. Although, that will be an appreciated residual effect! For me, its more about a best of both worlds strategy. Bad ass launch AND cool runnings on long freeway/highway trips. We ALL know that you gotta get your RPMs up if you wanna haul ass in the 1/4 but, when you just wanna run down the freeway for a few hundred miles, the lower (to some point) RPMs you run, the more piece of mind you can have. If something is going to go awry, its WAY more likely to happen at high RPMs than low RPMs. I'm just torn between 700r4 with 3.42s or same tranny with 3.73s. 3.55s might be the ticket, too. IDK. Decisions, decisions...

    My gear ratios changed with my age, the older I got. lol
    1968 Chevelle 4.56
    1970 Z/28 4.10
    1972 Nova 3.42
    1970 SS Camaro 3.31
    I think some of us older folks like less buzzing.

    I just did a swap from 3.08 to 3.73, with a 4 speed, 235 60r15 around 3000rpm @ 80kph(48mph)...what a difference! My 327 absolutely loves 3000rpm! It made the car so perfectly drivable in town as well as highway. I wouldn't want to be on the freeway for more than a couple of hours but it is just a night and day difference and made it feel like a completely different car! Thumbs up for 3.73!

    So about an hour ago I finished buttoning up 3 days on my back working on the Camaro..... man am I liking how quickly those 3.73s get up. I am still breaking the new axle in but man.... it is already fun taking off from the stop lights!
