With a 3.00 rear you should be turning 2200 at 60 mph + about 100 rpm slippage in the converter. So at 70 (2300 : 6 = 370 x 7 = 2590 rpms at 70mph. my 57 Ford (3.70 w/OD) turns about 2300 at 70. Another words I don't think you will gain anything , or very little, going with O/D. You can not run a 3.00 rear with O/D as I don't beleve you will have enought power at the rear wheels to move the car. Gas engines in boats are set up to turn 3000 to 3200 RPMs under load all day long so you are well within you safety range with the 3.00 gears. |
