    Somebody help... i am doing a 59ab into a 30 sedan. I have a 8b transmission 3 speed with overdrive. Can that fit on my motor. Or does anyone have any ideas instead of a t5 conversion or aod. Thank you so much.

  2. You will need a bellhousing adapter or the "hogshead" from a '40's truck.

    Here is another option if you can find one the 49-50 Mercury trans bolts right up to the 59 series block

    My guess is that its from Model Engineering (MEC)

  12. I used the MEC adapter at first in my 8BA powered '35 sedan with a 3.55 rear. Really a 3 spd + OD in 4th. I didn't like the ratio spread in the gears and needed a lower 1st gear so changed over to a T-5.

    There is a big jump from second to third and another big jump from third to fourth. But it's at the sacrifice of having the shifter in the right place

  14. Would it be better with 3:78 rear gears?
    And the rts trans comes in 2 different ratios,a close and wide,Which is better?

    RTSDecodingTable.jpg There are actually 3 different ratio sets in the RTS transmissions. Mine has the tallest overdrive gear of .70. I have 3.78 rear gears and 7.00 X 16 rear tires. That all translates into 2000 RPM at 70 MPH. Ideally I would try to get the .78 overdrive version. So, to get e little more RPM at 70, I have a set of 4.44 gears I am going to swap in, but my first and second gears are about right now. I don't think the 4.44 wont have as much affect on the final drive ratio in first and second as it does on the overdrive.

    I got myself a hogshead adapter for 80 bucks... i think i am going to run the t5 ford. I read good things about this execpt the shifter location is further back

  19. That can be fixed with an 80's s10 tailhousing,or use an s10 t5.
