    can i take my brand new 350 motor that is mated to a 700-r4 tranny and connect it to my th-350 tranny which currently has a blown motor on it?

    this arrises from my situation in may, when i totaled my jimmy. we have decided to swap it into my 81 project, but i want to know if i will have to get an adapter for it.

    That 350 out of your 88 that you wrecked (I think that is the wrecked one that you speak of?) will bolt right up to your th350 trans in the 81. You will probably have to put the torque converter and flywheel off of the 81 onto the motor that came out of the 88 before you bolt it to the th350 though.

    The 88 flexplate/flywheel will not bolt to the 81 engine or vise versa.

    You need to get an flexplate for a 1 piece rear main seal motor (86 or later)
