Are you sure the torque convertor is seated fully in the transmission?

Another good point Frank. It's VERY easy to NOT fully seat the torque converter when installing it onto the transmission.

If the TQ converter wasn't seated onto the input shaft..... it would have been a bear to mate the bell housing to the rear of the engine block. So much so that tightening the bell to block bolts would result in "bending" the flex plate forward. The flex plate isn't going to bend much, but if the OP had a gap between the bell and the rear of the block that would only close by tightening down the bolts... it could be enough force on the face of the flexplate to force it into contact with the blockplate.

frank, i think you're right. i went to a wrecking yard that specializes in mustangs, A & M Wrecking, in Rio Linda, and the owner, Jeff Guy, couldn't be more pleasant and informative. we talked about the possibility of a shim or spacer....he gave me one, but didn't think that it was the solution. he said that he didn't remember fords needing to be shimmed. anyway, he brought up this torque convertor issue and i do recall that my buddy had a hard time seating the convertor. he did recommend that i pull the trans and check the convertor to see if the flange is "squished", indicating that i was forced into place. so....thank you all again for all the awesome tips. i was hoping to not have to pull the trans, but i'm going to have to do it anyway and restart. i'm also concerned that my flywheel may be bent or that the forced convertor may have damaged the pump. wish me luck. i'll try to take pics.

ok, so I'm going to tackle this trans removal tonight and was wondering.....while I'm at it...should I install a shift kit AND a new higher stall converter? anyone recommend a particular one?
here's the specs for the motor:
late model 302 short block, 9.5:1
gt40-P iron heads
E-303 cam
1.7 roller rockers
air-gap/rpm intake
demon 625 carb
tri-y headers
2.79 open diff rear.
i plan on running the stock 14" wheels until i can get 17's. i've read some info on TCs and i think the "mild" street ones are where I should be...around 2500-2900 rpm. if not stated earlier, this is the orig C4 in the '67 coupe. thanks everyone!!
