can the 4l60e hold up as a drag trans pushing 600-700 hp? or should i change over to a different type transmision?

If your building a drag car that wont see much, if any street, build a TH400. Much stronger than a 'built' 4L60E.

will a th400 be fine on the street it wont see much but i want to play with it every once in a while.

I know/met people that do drive them on the street, sure. It wouldnt fit MY standards of DDing, it might you though.

No overdrive is a killer for me. Besides that, its an awesome transmission.

well the way chevy brakes things down is like this
4L60E

4 - number of gears
L - Longitudinal, meaning its for rear wheel drive
60 - HP rating, you mult by 10, divide by 2, so its rated for 300 hp
E - electronic shifting.

so without the E, is the old ones, 4L60, before electronic shifting. 4L80E, same trans, but handles 400 HP.

TH400 is solid, so is the 700R, but I dont know much about them.

The only bad thing about a turbo 400 trans is that it will eat gas mileage bad. If you only cruise it once in a while don't worry about it. It won't be much worse than a pickup.
