351w swap AODE TQ converter to flexplate issues

bones94gt · Jun 4, 2012

hey guys,

first off I did do a quick search came up with nothing! The problem i am having is when i stick the tranny and engine together the flexplate and tq converter hit before the block and tranny are together causing a bind. i have made sure the tq converter is fully seated in the tranny on the pump flats and i have a 164 tooth 28oz flexplate and the TC snout is not hitting the crankshaft it has plenty of room i have measured many times and also measured how far the converter is into the tranny from the bolt pads and its around .950 and then i measured from the back of the block with the block plate and get just over and inch so theres my problem but cant figure out how to fix it. all the flexplates i have see or measured come up the same or with in like .030 but i need to make up like .150. a little about the combo 93 ford lightning 351w short block and its going into a 94 mustang gt with an AODE tranny. I am wondering if anyone one has ran acrossed the same issue or if anyone has any ideas.

ALSO I have measured the distance the tc should go into the tranny and the measure the tc inself and see where it lands and it shows its seated all the way i also can hear the tc bottom out hard when i get in on. any help will be apperciated thanks matthew

Hmmm. I guess the logical question to ask here is where did the torque converter come from and where did the flywheel come from. We all know that an AODE will bolt right up to a 351w block because it's the exact same bolt pattern as it's little sibling the 302. So the mismatch MUST be in the TC and flywheel relationship.

i thought the same but i have measured and compared the flexplate to the factory plate and there with in .02 of each other but the flexplate is an scat fp-302e sfi and the tq convertor is a AODE precision industry. I am starting to think that maybe the tc was just made slightly to long because the guy that owned the car before kept burning up the thrust in his engines and he was running the factory 302 and flexplate. but never hurt the tranny. I did call precision and got there opinion on things and they gave me somethings to try but i am certian the tc is seated because i can hear and feel it bottom out and i can also feel it slid in and out of the tc flats.

Maybe get the measurements from a stock TC and compare then to the one you have. I don't think a difference in flexplates would be easy to miss and besides, TC's are usually custom made anyway aren't they? A lot of human error can happen in a TC's manufacture!

sfi flywheels seem to do this.. get another block plate and double them up may fit we had similar problem with a c4 install had to get another block plate due to flywheel being cut different..
