I recently swapped pumpkins on the 8 inch. I went from a 2.79 to a 3.00, both are open, stock units. I did not expect the change would be that much, but it is much more than expected. I am thrilled. It drives like a totally different car. It pulls well in all gears, and I can putt along in 4th or 5th w/o lugging the motor. I have the 200/6 with a T-5 from a 4 cylinder mustang (3.97 1st gear, and a .085 OD) This was a 6/8 drivetrain conversion, so a stock 8 inch w/2.79 gears was installed along w/ T-5. It ran pretty good like this. I then purchased a CL pumpkin, w/ 3.oo gears, and did the swap. I think my gas mileage will greatly increase, as it is very happy cruising w/ very little throttle input. It also pulled good to 90 on the highway in 5th. I did not expect to see much change since these 2 ratios are so close together. The car had a 3.2o gear with the 4 lug set up. I never had much seat time due to many other issues with carb, ignition, suspension, & steering. But now it just purrs along. When I had the 2.79, I had to keep the rpm's up (read: keep my foot in it) and I had to shift alot. Lo speed cruising-25-40 mph was difficult.5th gear was also difficult, as I had to be going about 60mph to shift into it w/o lugging the motor. Now it is smooth and cruises in 5th from 45 mph and up. Time to start tracking gas mileage again.
