I just finished a complete engine re-build and a tranny swap, the engine runs great but when I put it in gear I have very little power. I have done a complete vacume check, checked for brake drag, changed the carb step-up springs set and reset timing and replaced the modulator, the thing still acts like a dog. This has lead me to the torque converter I think the new one is only stock. Could the moderate Cam I put in be causing the problem. In neutral I have to set idle @ 950-1000 rpm to make the engine run right and to put it into gear without stalling. I am considering going to an 1800-2000 stall converter. I just want to know if anyone else has had this type of problem befor and if I'm on the right track.
