Torque Converter Change

I've been disappointed with the performance of my Trans Am since I put the 400 in. It just didn't seem to have the "seat-of-the-pants" feel as it had with the Olds 350. I put the torque converter in that was behind the 400 instead of the one that was behind the 350 because I figured the one that was behind the 350 was a 2500 RPM stall and Pontiac engines were supposed to make torque right off idle. It didn't work out to my advantage. The 400 fell flat on it's face with the converter that was behind it when I got it. So I thought I'd try the one that was behind the 350. It wasn't an easy change. Some of the bolts that had nuts in places I couldn't get a wrench on. The cooler lines were a pain when I put the engine in and they were just as stubborn this time, too. The dip=stick tube was a pain, too. Michelle came to the shop to take me to get a converter seal, filter and gasket and some fluid. She decided to stick around and help out. She wasn't afraid of the dirt and grease even after I warned her. She did a great job helping out. I fought the first cooler line on and she wisked right through the other! She held the light for me when she wasn't helping with those bolts with "the impossible nuts". She even helped to get the dip=stick tube lined up and installed. She was great! I didn't get it completed Friday night, I had to go in Saturday to finish it up. I had a lunch appointment with her for a birthday party. I had to get cleaned up and leave for that, but came back afterwards and finished it. While I had it in the shop and on the hoist I decided to weld up the exhaust leaks. Well when I started it up, it sounded great without the leaks! So I pulled it outside so I could sweep the floor. I did a little brake torque. It wouldn't turn the tires over before, but it did this time! I took it out for a test drive and on home with it. There's still something amiss with it. It stumbles before it goes, but it doesn't fall on it's face. I think it's in the carb. I'll have to figure it out, but for now I can honestly say I'm headed in the right direction!

I think the carb has taken a **** on me. The engine won't rev up when you mash the gas like before, it just bogs down and slowly revs up.
