68 I6 to sbc auto, few questions
so ive done spome reading getting the most for the swap.and i think i know my answers but need to clarify.
i have a 68 frame,factory inline 6 and manual trans.both gone.peches and member still there. i have a sbc 350 and th400 from a 3/4 ton 69 gmc.(factory v8 auto) my questions are- are the v8 perches from a 3/4 and 1/2 the same?do i need to buy them for a 1/2 ton? and are they different between 68 and say 69 or 70? factory driveshaft is still there. will the yoke slide into the th400, or do i need to use the yoke currently in the th400? as for the transmission crossmember, i have a factory crossmember for a th350 automatic out of a 69.can i use this with the th400 on the 68 frame? i know with the v8 perches it moves up a hole from the straight 6 engine.i could just jump right into it and notice what i need as i go but man if anyone knows these and could help itd be sweet! i know the answers are somewhere on the board, just beating my head in with 5+ questions.thanks guys ![]()

You need to use the TH400 yoke. It is larger in diameter. I think you can use the TH350 Xmember. I posted some pictures of the two in this thread.... http://67-72chevytrucks.com/vboard/s...d.php?t=241552 You will have to remove the manual trans Xmember. LockDoc

When you remove the manual trans crossmember, drop me a line. I need one.
