I searched and found a couple of tidbits. But I wanted an answer to this issue in a more direct fashion.

I have a built 1973 Small Block 400 that I'm considering selling, IF I don't use it. The car it would go into is a 1993 Caprice Police Package with the 4L60 (No E) aka 700R4.

So I need a special flexplate OR will the 400 stock flexplate bolt to the 700R4's torque converter?

Thanks for the info guys.

 

The 700 converter will bolt right up to the 400 flex plate.

 

Excellent. That is exactly what I wanted to know. Thank you for a straight-to-the-point answer.

 

If the 168-tooth, 14" starter ring clears the TH700 bellhousing, that is. You might want to try bolting them together w/o the torque converter to be sure.

 

It does. BTDT.
