PG vs. th350/400 on the street

[kicker91laser]

What is your opinions on a powerglide trans vs. a th350/400 trans on a street/strip car? Please discuss.

I know that the PG is recommended for the track, but how have you guys liked them on a street driven/non daily-driver?

PG will give you the most mpg, less hp to turn. 350 will give you more than a 400 also. 400 is the strongest, probably will never break it. Of course, I am a little biased, I have been running 400's since 1980 except for a few months in 85 when I had a 66 Chevy 1/2 ton with a 350/PG combo. Man, those were the days.

You have to compromise. The TH400 would be best on the street but the powerglide has been a lot better for me on the strip.

I'd run the three speed on the street just because of the lower first gear ratio....it will be more fun to drive.You're not looking for consistancy just something fun to drive. Just my opinion.

[russ67chevelle]

th400 gets my vote, ive seen mid 8s with mine in the quarter :D

[OneBadGMC]

Mileage? We don't worry bout no stinkin mileage.

T-400 all the way. It can hold a ton more power than a comparable PG, and to build a PG to hold the same power costs a LOT more.

[russ67chevelle]

i gotta laugh gmc you are soooooo right!!! on my th400 vehicles milage is not in the equation!!! :lol: :lol: :lol: i have three vehicles with em.best trans made for green horned hicks like me that dont wanna mess with the computer assisted trannies

I'm sure this has been asked before but I'll ask again. Has anyone ever swapped from a 400 to a glide with no other changes and if so what was the result? I am just curious about the gain or loss in ET between the 2. I know the glide is best for bracket racing but I want to know about which one will et the best in a 3200 lb BBC car...I don't care about consistant. 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.

Th-400, If you break one of them, there something wrong.

I am building a 70 chevelle right now and I bought a Lenco 4 speed, but after reading this post, it kinda of got me thinking why on earth I bought that lenco????????????? :cry: :cry: :cry: :cry:

[russ67chevelle]

ashbro u should run faster dont worry

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.

[ARUSSELL]

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.

[kwkracing]

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

[CamBirdRacing]

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.

[newjack42]

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.
