    I'm in the process of building a '78 drag only car. Power will be made by a 700 hp 496, naturally aspirated. I want to stick with leaf spring rear end and will probably use Cal Tracs bars and a 9". The car will be fully stripped with a 10 pt. cage. My current guess at the weight is around 3000. Would I be better with a TH400 or a PG?
    Thanks for all your help!

    Go with the glide. It'll hook much easier than a 3 speed and there are parts galore available for it.

    I think I would agree with MikeA. The general rule of thumb is 2900 pounds and lighter, the car would be quicker with a glide, above 2900# use a 3speed. Your making enough torque with the big block that I doubt you would want the deep first gear unless the car hooks hard enough to toss the skinnies up into the ozone. With that much weight on the nose I'm sure traction problems are going to be the challange. A glide with the 'right' convertor would definately be my choice there.

    Since I'meccentric(others say weird) I use a 350 Turbo.
    Lighter than a 400
    Can be built strong too.
    And ya get to shift more with a turbo than a PG

    I'm weird I guess as well since I like the 350 for the same reasons as hot and with my nitrous I'm over 800hp and have had only one problem with 2nd gear failing but I don't have all the good parts in it yet and think it will stand up with a little more money spent on it.I would however choose the glide over the 400 in your case if you don't want to go 350.

    I think the car's too heavy, and the big block make too much power for a PG, go with the 400.
