Hey Wrenchbender, I was planning to remove the 350 for a 250 or 292 six. My flexplate for the 350 has a balance weight on it. I hoped to just bolt in the six but had been told the output shaft and etc was wrong for this set up. I'll go down to the parts store and see about the flexplate how it matches up to my torque converter. I bought a new stage 1 converter. Thanks very much. I love this site. Its the best. H.
