My SBC Corvette runs hot, around 230 on the highway and is a problem. I'm in the process of planning some upgrades/mods to get this under control. An OD trans swap for my TH350 has been considered for a .67 OD gear. Another option is a Gear Vendor unit that splits all the gears, but that is no advantage for me, but the .25 OD is. This equates to dropping my highway RPM between 400-500 RPM. This is not nearly as much as a
200 4R or 700R4 will do on the highway. Does anyone have any experience with a GV unit or thoughts on swapping one in? I might add that my car is a bracket racer that is driven to the track. My J&W built TH350 serves me very well and could be kept with a GV unit and shortened DS. A refurbished unit can be had on fleabay for $1700 and about the cost of upgrading to an OD trans. Anybody have any experience with these GV adapters?
