I just wonder if the lower first gear and harder launch with the 400 will be offset by the extra hp needed to turn it. I just horse around with my car and have fun, so consistancy doesn't concern me much. It dead hooks with little burnout with a glide...60' is low 1.30's I just was thinking of putting a 400 in it for fun.

I went for a t350 to a 1.76 glide #3000 car and my 60ft stayed the same mph same et same.

It just don't lift the front wheels off the ground anymore. :cry: :cry: :cry:

It depends on your weight and engine. A glide worked better in my application with a light car and blown engine on the street. When you put a 3 speed in gear, and drive it, if you have a stall above 3000 there are two many gears, the convertor never locks up cruisen around an makes alot of heat. If its light, a glide. If its heavy a th400 for sure

If it were me Tod> I'd stick 200r4, lower first than T400, if you tear it up, no sweat, just go to the junkyard and grab another one for $50 :lol:

I may do that so I can brag that my car was so powerful it destroyed the trans.

I am a TH350 fan, just expensive to build when you start putting any real power against it. I have had bad luck with breaking cases on 400's.

A turbo 350 fan? I have heard it all now! And 400 cases crackin?

I broke the bell housing on my 400 last year. Put a new bushing, seal and a JW bellhousing and still racing it. Broke many 350's. Usually at the tailshaft.

400 all the way. i have to run a 350 or a PG in my dirt mod. easly go threw 2 or 3 a year no matter how much money you stick in to them.
used 400's in pullin and mud trucks never once a problem with them.
