i am getting ready to go to an auto in my 2wd blazer my question is is the 700r4 really woth it as i figure with the 3.07 rearend i currently have with a th350 my final gear will be 3.07 and with a 700r4 i would have to chenge to a 3.73 rear but i would end up with a final drive gear of 2.83 so do you guys actuall think the difference between final drive gears (.24) is worth the extra money for the trans and to change the rear?

also the 700r4 i have has an electric speedo. do you know what or have the parts i need to go to a mechanicle speedo?
