Default PG vs. th350/400 on the street

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.

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.

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.
