The Stovebolt Site Forums The Shop Area Engine Shop Saginaw 3speed OD for my 37

Well, The OD got it's first road test yesterday, works just dandy. The 261 just burbles along at 1800 rpm at 60 mph.
Wrench, my 37 does have 3.36 gears and the rpm is around 2500 at 60 mph in direct drive.I like the 30 percent drop in rpm, no problem at all.
17 percent OD on new cars? Most stick trannies in rear drive vehicles have around a 30 percent reduction.My 4.3 powered S10 has 2.73 gears and a .73 OD ratio in 5 th gear, runs along at 1500 rpm at 60,great for fuel mileage anyway.
