At this point, I have basically completely been sideswiped with new, extra, other questions that I have decided it is time to know what the parameters of what needs to be accomplished so we can really figure out what is wanted instead of trying to answer hypotheticals for a person that probably has less money than I do, putting 90percent of the answers out of the ballpark from becoming a reality.

With that, here is a simple description of a 4spd to 4spd would be geared in simplicity.

1st 4:1

2nd 3:1

3rd 2:1

4th 1:1

Second transmission the same

Rear end 4.0:1 for simplicity

1st to 1st to rear end would be 4:1 times 4:1 times 4.0:1 or 64.0:1 ratio at the rear wheels.

2nd to 1st would be 3:1 times 4:1 times 4.0:1 ratio to the rear wheels as 48:1

3rd to 1st would be 2:1 times 4:1 times 4.0:1 which is 32:1

4th to 1st would be 1:1 times 4:1 times 3.0:1 which is 12:1 rear end ratio to the tires.

first to second would be 4:1 times 3:1 times 4.0:1 or 48:1

second to second would be 3:1 times 3:1 times 4.0 or 36:1 to the tires.

4th to 4th would be 1:1 times 1:1 times 4.0:1 or a true 1:1 ratio

So, as you can see, fill in the rest of the blanks and a normal granny four speed is around 4:1 times 4.0:1 rear or 16:1, and this is good for about 15miles per hour at redline, so look how granny geared this would be overall.

Now, again, what are you trying to accomplish as the main question?
