Should I replace my torque converter? I pulled the motor last week, its at the machine-shop and will return this Fri. The only real change to the motor will be new pistons and bored .030 over. The tranny is a turbo 350. My question is the motor is putting 350-370hp. Should I replace the converter with one that can handle that or should I stop where I'm at. The tranny has been fine up to now but I wouldn't mind a little more performance. Is changing the converter gonna make that much difference? And what would you put into a daily driver?

Is the transmission stock? High or low miles on it? How are you going to be driving your car? Hard, medium, lightly. City or highway driving?

Give some details about the engine. Example, cam specs, type of heads.....etc.

With more specifics, we can better help you with a good decision. I hate to see somebody spend the time and money on a build and not get the results they are looking for.

The transmission is stock, more than 100,000 miles. I drive it like I stole it. Mostly city and open it up on the highway once a week.

 The cam is a 268 grind, I dont have the card here but i think it has a 220 intake and 220 exhaust, I dont remember the overlap.

 Weiand Stealth intake with 625 Road Demon jetted 64 in front 74 in back. Dart iron heads 194/150 stainless valves ported/pocket ported prviding 10:1 compression. The new pistons are dish pistons. Hooker headers  with a 2.5 exhaust.

3:73 gears with GrandAms. I haven't made a final decision on tires.

 I appreciate any input as i know very little about automatic transmissions. I was always taught that automatics were to be replaced with a good manual. But with this car I wanted to see what I could do with the turbo 350.
