thanks for the replies guys. as for questions? we took it to 6500 rpm.i did seat the converter carefully when installing it.all motor and tranny mounts are new rubber mounts.all mount bolts are new and torqued.the car came stock with a 'glide,my understanding is 'glide to th350 is a straight swap,with the exception of shifter linkage and detents.i am taking the driveline to be checked/balanced today.thanks dan
