    4 spd or th 350

    OK long story short my muncie took a crap today and I have a th 350 layin under the bench with a shift kit and 3500 stall convertor in it. Am I gonna gain anything other than consistency with the auto?? I like rowin thru the gears but if I can knock a couple tenths off my ET it would be worth it.

    From what I hear automatics are faster than sticks. I just dont know bout the converter. I am still new to drag racing and am trying to learn as much as I can from these guys on here.
    Its all fun and games till someone loses a nut!

    I think it will depend on your skills with the standard shift .

    with your car being so heavy you should go with the 400.

    the 1 2 shift is brutal on the sprag if it is built,But if ya got it,smoke it.

    oh,I don't think it will be faster

    the other thing is this a really nice car? SS, or Original 4 speed

    I believe it is 2.52 1st gear and the TH400 is 2.48

    NOT 100% sure but I do know those numbers are really close.

    They are easy to find for a Chevelle.Just look in a restoration catalog but be prepared to pay about 5 times what they are actually worth.
