Good info here... question: is there any advantage to using the 4L60e trans versus the 700R4? I'm going to upgrade out of the TH350 on one of my stock '76 C25's - I do a lot of highway driving and the mileage isn't too good when the engine winds up. Need the overdrive. BTW, what's the diff ratio on your rig? --Rob
