    So I have a Th350 in my camaro 1974, I have a 350 v8 thats kinda just stock right now.It has a floor shifter.
    I was thinking of either restoring this engine and upgrading it, or dropping a big block 454 in there.

    Either way. I want a Manual transmission. I was thinking to put a good manual from the time where it would ahve been made, which would be a 700r4 (correct me if im wrong haha) I believe.

    I'm not sure how that trans compairs to other transmissions (maybe a newer style/model?). Im not building it for performance just yet, so i would like if it was something that could support the high power later on.

    Someone told me that theres some ways to modify or buy a modified Th350 that can do a race start thats faster/better/whatever than a manual trans. Though i've always assumed manuals won over autos for performance due to lower weight and more control over the car.

    700r4 is an auto trans...autos are preferred for drag racing

    depends on WHICH manual your switching to.
    Muncie = easy peezy
    T10 = not a BIG deal but a few more parts
    Saginaw = why bother
    Tremec 600 = little complicated, a few special parts.

    1 question. How much money do you expect to spend?

    NOW multiply that times 1.5

    NOW you should be close.

    350 auto vs manual trans

    If you want to have fun with your car, 4-speed is the way to go. I like the original Muncie 4-speed. Find one with fine spline input shaft and a 1 inch counter-shaft and you will have a very sturdy trans. Also, there are plenty of vendors still making parts for these trans. The car is very easy to swap to a four speed. Places like NPD sells a kit with most of the parts.

    Thanks for the responses haha!

    I think I might just do a Muncie 4-speed. Seems to be the cheapest and easiest of the solutions.

    Honestly i'm not sure what my budget for this is, but i do want to swap this transmission while i have the itnerior gutted so i dont ahve to do it later.

    just how easy would it be to swap my th350 for a muncie?? do i need different driveshafts or what?

    EDIT: I looked on NPD real quick and i didnt see a th350/400 to Muncie :(
