RX-Snake: Transmission
joedls, or ayone else:
What are the ratios in the Top Loader: 1st ? 2nd ? 3rd ? 4th 1:1 I have a great spreadsheet for plugging this stuff into so you know what your mph/rpm curves are. I would really like to carefully consider the whole system for optimization, from engine through trans to axle and tire size |

Depends on whether it's a close ratio or wide ratio. I'm not sure which one yours is. Wide ratio: 2.78 1.93 1.36 1 2.78 reverse Close ratio: 2.32 1.69 1.29 1 2.32 reverse |

I've always prefered Wide rations over Close for the street. Now, on a Drag car the % of drop between gears should be ABOUT 19% per gear ( if my brain is working right ). Now that is what we used in the Seventies. What is the current diff gear ration on the RX? The Wide Ratio will be fine in most cases. We can make it work. We can not do better --as far as strenght for a 4 speed-- than that Top Loader.:thumbs_up: Some poor anal restoration guy is looking for that trans for his 64 Mustang.:smack: |

Yeah, and he might be willing to pay a stupid price for it. Though I don't know about the 289 model. It's the 427s that go for big bucks. According to JOe the ratios are: Wide ratio: 2.78 1.93 1.36 1 2.78 reverse See the engine thread. I posted a graph of mph:rpm assuming this gear box, 255/60x15 tires and a 3.73 rear end, which I *think* is what's in there now, but I need to check. |

I was offered $800 for that tranny from a guy that just wanted a toploader. It would be worth more to a guy that is looking for a correct date coded tranny. |

Nah, they're too damn ugly for me. I just wanna drive the car and I couldn't let them put a SBC in that car. :rolling: |
