aod to c4 swap Reply #3 – September 05, 2008, 03:06:32 PM It's Still A Lil Off, The C4 Bolts Are A Lil Wider, I Took A Piece Of Thick Steel And Drilled Holes And Bolted It Down, Exhaust And Stuff Didn't Line Up By Flipping. Quote Selected

aod to c4 swap Reply #6 – September 13, 2008, 02:40:03 PM i got a panfill c4 with converter, and i have to double check but i think it will fit the 164 tooth flywheel. the c4 got the big bell from what i`ve learned from the net. i hope to get the tranny in tomorrow. I have to mod the crossmember, think i can move the bushings backward to get the crossmember forward. i think hehe :hick: Quote Selected

aod to c4 swap Reply #11 – September 15, 2008, 04:30:03 AM well, i got the trans in and prop shaft in. Every thing bolted in except i had to mod the crossmember a little. Now i just have to shifter and oil lines hooked up and add some fluids. Any tip how to get the kick down to function right, i`ll get it to work but i`m sure some one has done this swap before with great resault.i hope to get the aod rebuilt this winter because the gas is like 8,5 $ pr gallon here in norway!!

aod to c4 swap Reply #13 – September 22, 2008, 04:13:12 AM hi.The car is now runnig again. the swap was a relatively easy swap. worst part was getting the engine/trans bolts bolted up. It was not much room to turn the tools there Had to bypass the neutral switch (easy)The car feels different to drive, i dont know why but it fells quicker and lighter.It is fun to drive my T-Bird again :burnout: Thor Quote Selected
