flexplate

[crosby]

I have an 87 K20 pickup (on a mid 70's frame), and a 350 I pulled out of an 87 Jimmy (FI). The pickup is an auto, the Jimmy was a standard. I bought a flexplate for the engine, and it turns out that the hole in the middle and the bolt circle is too big for the crank. Is there a different crank for standard shift engines? Also, when installing an engine, do you bolt the flexplate to the torque converter AFTER you install the engine? Thanks very much for your help guys!!
