High Class Problem

[AndyMoriarty]

I could use some advice/opinions to help me made a decision on a built 700R4 versus a Gear Vendor Overdrive bolted to a TH400. I have a 69 GMC with a 502 Ramjet (510hp/560torque) mated to a TH400 into a 12 bolt posi with 4.11 gears. I intend to take it on the long haul Power Tour next year and desperately need an overdrive gear. The truck is not raced but driven hard between lights. My most important goals are to get a highway cruising gear with very high reliability. I like the idea of simply installing a Monster 700R4 but I am concerned about its reliability versus the much more expensive Gear Vendor Overdrive. All thoughts and opinions on thye pros and cons are appreciated as I need to make a decision.

Best Regards and thanks.

Andy
